Here is a sample problem from an old exam on periodic digital waveforms

For the square wave shown below, determine its (a) Period, (b) Frequence (c) Duty Cycle and (d) Amplitude

square wave

There are 4 parts to this question.

But there are 8 possible points. 1 point for each correct answer, 1 point for each correct equation shown with correct values substituted

A) Period


B) Frequency


C) Duty Cycle


D) Amplitude
