- An ac amplifier has a midband voltage gain of 200 . If the cutoff frequencies are \( \mathrm{fl}=20 \mathrm{~Hz} \) and \( \mathrm{f} 2=20 \mathrm{kHz} \), what does the frequency response look like? What is the voltage gain if the input frequency is \( 5 \mathrm{~Hz} \) ? If it is \( 200 \mathrm{kHz} \) ? - A \( 741 \mathrm{C} \) op-amp has a midband voltage gain of 100,000 . If \( \mathrm{f} 2=10 \mathrm{~Hz} \), what does the frequency response look like? What is the voltage gain for each of the following input frequencies: \( 100 \mathrm{~Hz}, 1 \mathrm{kHz}, 10 \mathrm{kHz}, 100 \) \( \mathrm{kHz} \), and \( 1 \mathrm{MHz} \) ?
