Finding the coefficients, F’ m, in a Fourier Sine Series Fourier Sine Series: To find F m, multiply each side by sin(m’t), where m’ is another integer, and integrate: But: So: ! This is likely because a somewhat greater percentage of the pulse’s energy is concentrated at lower frequencies, and so a greater percentage is within the bandwidth of the filter. Periodic Pulse Train - an overview | ScienceDirect Topics The duty cycle for a rectangular pulse describes the fraction of time that the pulse is on in one pulse period. Within the ultrasonic stimulation pulse train, each pulse had a pulse duration of 30 ms and a pulse repetition interval (PRI) of 100 ms for a duty cycle of 30%.
