dutyCycle(a)

Determines the duty cycle of an arbitrary signal.

Syntax

o_dutyCycle(a)

a: waveform - signal to be analyzed

return: scalar Real- duty cycle of the (presumed) periodic signal

Usage

Returns the duty cycle of a signal, as defined by 10-90 transitions between a "high" and "low" value.

Location

menu: veeos ==> Signal Processing ==> dutyCycle

library: sigLib

Example

see example in veeos menu

Notes

One common parameter for digital signals is duty cycle: the relative time spent "high" vs "low". This is normally presented as a ratio, with "1" being "high all the time and "0" being "low all the time". This function uses that standard and defines "up" as within 10% of highest value and "down" as within 10% of the lowest value. Given these margins the function is resistant to noise in the signal, but of course gets best results with many cycles.
