Consider a series of amplifiers and feedback circuits connected in the ideal feedback configurations. In each case the input resistance to the basic amplifier is \(R_{i}=10 \mathrm{k} \Omega\), the output resistance of the basic amplifier is \(R_{o}=1 \mathrm{k} \Omega\), and the loop gain is \(T=10^{4}\).

(a) Determine the maximum possible input resistance and minimum possible input resistance to the feedback circuit.

(b) Determine the maximum possible output resistance and minimum possible output resistance to the feedback circuit.
