Expert Solution
Step 1: Summarize the given information.

The output of a push-pull amplifier is given as

y open parentheses t close parentheses equals open curly brackets table row cell A sin open parentheses capital omega subscript o t close parentheses plus A epsilon end cell cell t element of open square brackets 0 comma T over 2 close square brackets end cell row cell A sin open parentheses capital omega subscript o t close parentheses minus A epsilon end cell cell t element of open square brackets negative T over 2 comma 0 close square brackets end cell end table close.

Its fundamental period is T equals fraction numerator 2 straight pi over denominator capital omega subscript o end fraction.


To determine:

  1. Fourier series representation of output signal y(t),
  2. expression of the total harmonic distortion, and
  3. harmonic distortion for epsilon equals 0.10.
