For Vᵢₙ=10sin(2πt) applied to the circuit shown, which output waveform results? Both op-amps have ±12 V supplies. The second stage contains 100 kΩ,0.2 μF and a 10 kΩ feedback resistor.
The first stage is an open-loop comparator, so the sinusoid becomes a ±12 V square wave. The second stage is an inverting practical differentiator: its input capacitor responds strongly at each transition and then decays through the resistive network, producing alternating transient spikes. D shows this response rather than a persistent square, triangular or sinusoidal waveform.
