Webduty-cycle square wave, such as to make this waveform a unipolar square wave, by adding a d.c. offset (i.e. constant term) to the waveform, then this would only affect the a0 term in the Fourier series expansion of the waveform. For an upward-shifted unipolar square wave of … 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. For example, a signal (10101010) has 50% duty cycle, because the …
