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? In electronics, duty cycle is the percentage of the ratio of pulse duration, or pulse width (PW) to the total period (T) of the waveform. It is generally used to represent time duration of a pulse when it is high (1). In digital electronics, signals are used in rectangular waveform which are represented by logic 1 and logic 0. Logic 1 stands for presence of an electric pulse and 0 for absence of an electric pulse.
