Problem

A square wave of peak-to-peak amplitude

2.0\,\mathrm{V}

and fundamental frequency

f_1 = 1.0\,\mathrm{kHz}

passes through an RC low-pass with

R = 2.2\,\mathrm{k}\Omega

and

C = 15\,\mathrm{nF}

. ((a)) Predict the corner frequency of the network. ((b)) Predict the peak amplitude and phase, relative to the input, of the fifth harmonic (

5.0\,\mathrm{kHz}

) at the output.
