Question

A sinusoidal signal with a peak amplitude of 10 V and frequency 1 Hz is applied 
to the comparator circuits shown in Fig. A2b(a) and Fig. A2b(b). For both the 
circuits, the op-amp is powered by a ±VCC of ±10V with the corresponding 
saturation voltages ±Vsat of ±9 V, while for the circuit in Fig. A2(b), the values of 
R1 and R2 are 10 kΩ and 25 kΩ, respectively. Assuming that the signal 
frequency is well below the slew rate limit, describe and draw separately what 
would be the comparator output (Vo) for circuits shown in Figs. A2(a) and A2(b).
