(a) Design a passive \(R C\) first-order low-pass circuit with a passband gain of \(\mathrm{odB}\) and a cutoff frequency of \(5 \mathrm{krad} / \mathrm{s}\).

(b) Cascade two identical circuits of your designs in (a). Using Multisim, plot the output of both circuits on the same graph using \(\mathrm{dB}\) for the magnitude. Then discuss what effect on the cutoff frequency and the roll-off (final slope) cascading had on the overall design.

(c) Suppose we insert a follower between the two stages, will the cutoff be at \(5 \mathrm{krad} / \mathrm{s}\) ? Explain.
