In a voltage shunt feedback amplifier, the output waveform is determined by analyzing the circuit behavior with the given input signal. The output waveform will be an inverted amplified version of the input signal due to the shunt feedback configuration.

For a sinusoidal input signal, the output will be a 180-degree phase-shifted sinusoid with amplitude determined by the closed-loop gain. The exact shape depends on the feedback resistor values and the input signal amplitude.
