Extra exam question E7G02

WhyAdding a capacitor across the feedback resistor in the Figure E7-3 circuit gives it a low-pass filter frequency response. Adding a capacitor across the feedback resistor in the Figure E7-3 inverting amplifier reduces the feedback impedance at higher frequencies (since a capacitor's reactance falls as frequency rises), which reduces the circuit's gain as frequency increases, giving it a low-pass filter response, answer B. It doesn't create a high-pass, band-pass, or notch response, adding capacitance in the feedback path specifically rolls off gain at the high end.
