  2. Pulse width - Wikipedia

    en.wikipedia.org/wiki/Pulse_width

    Pulse width is an important measure in radar systems. Radars transmit pulses of radio frequency energy out of an antenna and then listen for their reflection off of target objects. The amount of energy that is returned to the radar receiver is a function of the peak energy of the pulse, the pulse width, and the pulse repetition frequency.

    Since a nonlinear medium will only produce the desired signal when both pulses are present at the same time (i.e. “optical gating”), varying the delay between the pulse copies and measuring the signal at each delay gives a vague estimate of the pulse length. Autocorrelators measure a pulse by measuring the intensity of the nonlinear signal ...

    Pulse duration using 50% peak amplitude. DECT phone pulduration measurement (100 Hz / 10 mS) on channel 8. In signal processing and telecommunications, pulse duration is the interval between the time, during the first transition, that the amplitude of the pulse reaches a specified fraction (level) of its final amplitude, and the time the pulse amplitude drops, on the last transition, to the ...

    The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. [3] Tachycardia is a high heart rate, defined as above 100 bpm at rest. [4] Bradycardia is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat ...

    Floyer wanted to develop a watch to measure the accurate pulse rates of his patients. Floyer created a watch that counted a user's heart beat for sixty seconds, it created an easier way to count and measure the heart rate of patients. Floyers' designs were physically made by Samuel Watson, who was involved in horology in the late seventeenth ...
