(a) In an inverting op-amp circuit, the nominal resistance values are \(R_{2}=300 \mathrm{k} \Omega\) and \(R_{1}=15 \mathrm{k} \Omega\). The tolerance of each resistor is \(\pm 5 \%\), which means that each resistance can deviate from its nominal value by \(\pm 5 \%\). What is the maximum deviation in the voltage gain from its nominal value?

(b) Repeat part (a) if the resistor tolerance is reduced to \(\pm 1 \%\).
