Question 3. The waveform shown in FIGURE 3(a) is applied to the input of the circuit shown in FIGURE 3(b) below.

a) Calculate the threshold voltage for the circuit. Assume the maximum output voltage swing of the op-amp is ± 3 V for when the supply is ± 5 V.

b) Make a sketch of the output waveform Vo, labelling the principal voltages.

c) Confirm you results by means of a PSpice simulation. Cut and paste the waveforms obtained into your assignment. Comment on any differences between values calculated in (a) above and those obtained in the simulation.
