A series-shunt feedback amplifier employs a basic amplifier with input and output resistances each of $2 \mathrm{k} \Omega$ and $\operatorname{gain} A=1000 \mathrm{V} / \mathrm{V}$. The feedback factor $\beta=0.1 \mathrm{VN}$. Find the gain $A_{n}$ the input resistance $R_{r}$, and the output recistanse $R_{v f}$ of the closed-loop amplifier.

Two amplifiers are connected one after the other in series (cascaded). The first amplifier has a voltage gain of 10 and the second has a voltage gain of 20 . If the input signal is $0.01$ volt, calculate the output ac signal.
