Duty cycle for square wave

WebThe square wave has a period 2*pi, has value +1 from 0 to 2*pi*duty and -1 from 2*pi*duty to 2*pi. duty must be in the interval [0,1]. Note that this is not band-limited. It produces an … WebMar 30, 2013 · However, the problem I am running into is the duty cycle input to the square wave is specified in percentage of period, whereas I need it to be in specified in milliseconds. How can I feed in the pulse width (in milliseconds) to the square wave's input? Do I need to perform some math on it?
