(a) Design a low-pass OP AMP circuit to pass only the fundamental and the next nonzero harmonic of a \(2 \pi \mathrm{ms}\) square wave. The gain of the OP AMP should be +10 .

(b) Find the first four nonzero terms in the Fourier series of the output of your filter.

(c) Validate your design using Multisim. The OP AMP's \(V\) \(\mathrm{CC}= \pm 15 \mathrm{~V}\).
