Question: (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)

(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.
