The key to obtaining a triangular output from an integrator with a square wave input is to provide
A) a constant-current charging source for the capacitor.
B) a constant-frequency charging source for the capacitor.
C) a constant-voltage charging source for the capacitor.
D) a short RC time constant.

Quizplus · Accepted Answer

A constant-current charging source for the capacitor in an integrator circuit results in a linear change in voltage across the capacitor, which, when applied with a square wave input, produces a triangular output waveform. This is because the constant current leads to a constant rate of charge or discharge, creating the linear ramps up and down that characterize a triangular wave.
