Unreferenced stub auto yes date December 2009 Pulserepetitionfrequency PRF is the number of pulses per time unit e.g. Seconds . It is mostly used within various technical disciplines e.g. Radar technology to avoid confusion with the unit of frequency hertz Hz mainly used for waves. There is however no clear or formal boundary for when to use the one or the other. Waves are thought of as more or less pure single frequency phenomena while pulses may be thought of as composed of a number of pure frequencies. The Multiplicative inverse reciprocal of PRF is called the PulseRepetition Time PRT , PulseRepetition Interval PRI , or Inter Pulse Period IPP , which is the elapsed time from the beginning of one pulse to the beginning of the next pulse. Within radar technology PRF is important since it determines the maximum target range R sub max sub and maximum Doppler effect Doppler velocity V sub max sub that can be accurately determined by the radar. Range ambiguity A radar system determines range through the time delay between pulse transmission and reception by the relation math text Range frac c tau 2 math For accurate range determination a pulse must be transmitted and reflected before the next pulse is transmitted. This gives rise to the maximum range limit math text Max Range frac c tau text PRT 2 frac c 2 , text PRF qquad begin cases tau text PRT frac 1 text PRF end cases math The maximum range also defines a range ambiguity for all detected targets. Because of the periodic nature of pulsed radar systems, it is impossible for a radar system to determine the difference between targets separated by integer multiples of the maximum range using a single PRF. More sophisticated radar systems avoid this problem through the use of multiple PRFs either simultaneously on different frequencies or on a single frequency with a changing PRT.

The Critical RepetitionFrequency CRF is a term used in gambling research to distinguish games of skill from games of chance. It is defined as the threshold of repetitions at which a mixed game becomes predominantly influenced by skill rather than by chance. Calculation and interpretation of the CRF The CRF is based on the idea that skill adds up while the chance elements cancel out in the long run. File Importance Skill Chance.JPG The CRF is the quantitative threshold at which the skill to chance ratio of the outcome of a game is exactly 50 . If a game is repeated more often than the CRFi, it is a game of skill, and, if it is repeated less often, it is a game of chance for the individual player i . If the statistical spread and the expected value of the player are known, it is possible to calculate the CRF by the following formula math CRF i lambda sigma 1i 2 over E 1i A x 2 . math The expression in the numerator describes the chance by using the variance of the scoring per game repetition for player i, being the confidence coefficient. The expression in the denominator is the expected value of a game x played by individual i, adjusted for any fees and represents the relative skill of this player against his opponents. Implementation The CRF is of particular interest to mixed games, e.g. poker , because the regulations of games depend on the predominance of skill or chance. For the legislator s decision, whether a game is to be classified as a game of skill or a game of chance, the CRF acts as an objective indicator which can also be converted into the playing time a player needs to reach the threshold of a skill game by multiplying the repetitions with its length.

PulseFrequency Modulation PFM is a modulation method for representing an analog signal using only digital levels 1 and 0 . It is analogous to pulse width modulation PWM , to which the reader may refer for more detailed information, as the magnitude of an analog signal is encoded in the duty cycle of a square wave . Unlike PWM, in which the width of square pulses is varied at constant frequency , PFM is accomplished using fixed duration pulses and varying the repetition rate thereof. In other words, the frequency of the pulse train is varied in accordance with the instantaneous amplitude of the modulating signal at sampling intervals. The amplitude and width of the pulses is kept constant. The advantage of pulsefrequency modulation is better immunity to noise interference than PAM. The disadvantage is more complex transmitter and receiver design. ref http www.aubraux.com dsp dsp modulation pulsefrequency pfm.php ref Potential Applications It has been proposed that PFM could serve as a suitable Visual prosthesis retinal prosthesis device. PFM s ability to operate independently and asynchronously promotes the flow of nutrient nutrients through the chip which is essential for living Cell biology cells . Cell stimulation would be accomplished through the output of pulse streams by PFM.

Instead of pressing the weight up slowly, in proper form, a Spotting weight training spotter generally aids in the concentric, or lifting, portion of the repetition while the lifter slowly performs the eccentric phase for 3 6 seconds. Negative reps promote hypertrophy greatly because they allow the muscles to experience extreme trauma. Everyone can lift with more weight doing negative reps.

Repetition Priming psychology priming refers to the finding that an initial presentation of a stimulus influences the way in which an individual will respond to that stimulus when it is presented at a later time. The response to a specific item that has been encountered recently a word, for example will be faster and more accurate compared to another item that has not. Repetition priming assesses implicit memory or non declarative memory , a memory system that does not require conscious awareness . For example, the faster response to a stimulus resulting from repetition priming will occur even if the individual does not consciously recall seeing that particular stimulus.

Repetition Blindness RB is a phenomenon observed in Rapid Serial Visual Presentation . Subjects are less likely to detect the repetition of a target stimulus physiology stimulus than they are to detect a second, different target. For example, a subject s chances of correctly reporting both appearances of the word cat in the RSVP stream dog mouse cat elephant cat snake are lower than their chances of reporting the third and fifth words in the stream dog mouse cat elephant pig snake . The precise mechanism underlying RB has been extensively debated. Nancy Kanwisher has argued that it involves failure to tokenize the second appearance of a repeated stimulus, leading to the second appearance being dropped from short term memory before it can be reported. However, Whittlesea and colleagues have argued that repetition blindness arises from a failure to properly reconstruct the list, both online and post list. This failure to properly reconstruct the list arises from the poor encoding cues that are the result of the RSVP task. See also Attentional blink Semantic satiation References Kanwisher, N.G. 1987 .

Repetition pitch is an unexpected sensation of tonality or pitch that often occurs in nature when a sound is reflected against a sound reflecting surface for example a brick wall , and both the original and the reflected sound arrive at the ear of an observer, but with a short time differential between the two arrivals. Echo When the delay of the repeated sound is too large, the observer perceives an echo when the delay of the repeated sound is generally smaller than 30 ms, he perceives the original sound only, but with a tonality coloration, pitch superimposed. Therefore, this perceptual phenomenon has been named Repetition Pitch RP . The perceived RP expressed in Hz equivalent is equal to the reciprocal value of the delay time T between the original and the repeated sound, or in formula RP 1 T with T expressed in seconds . RP is most salient when the original sound is wide band and does not produce pitch itself like white noise, which contains all audible frequencies in equal strength . Varied Sources Probably the first written report of the phenomenon dates from 1693 when Christiaan Huygens noted such a pitch in the wide band sound from a fountain repeatedly reflected against the steps of a large stone staircase in the garden of the castle of Chantilly in France. In an open field, one might be able to hear a gliding RP when a plane flies over. In music, the phenomenon is sometimes deliberately created by electronic means delay and add to superimpose a pitch or coloration effect on the original music see Flanging . In room acoustics and sound recording, however, the phenomenon often causes an unwanted coloration of the original sound. Uses Blind people might use RP to locate obstacles by clicking the street surface with their cane, thus producing a wide band impulsive sound that is reflected against the obstacle. In psychological and physiological acoustics, RP has been subject of various studies. External links http xs4all.nl fabilsen Repetition Pitch Repetition pitch ... more details
