Question

3) Consider the following repetitive waveform g(t). g(t) K I. 0 То a) What is the average value of g(t)? b) What is the duty cycle? c) What are An and Bn, show how to calculate and find the values in terms of nth harmonic (what is the final formula for g(t))? d) What is the power in the 4th harmonic (calculate a number? e) Plot the spectrum of a single pulse from the pulse train And plot the spectrum of the periodic pulse train ... On the same graphic. Superimpose both graphics.

Answer 1

As per HomeworkLib policy I will only answer first 4 sub-parts.
