The circuit is now modified to remove the 5 V power supply and instead provide feedback from the output (see Fig. A2d for the modified circuit). For this comparator circuit utilising positive feedback (commonly known as Schmitt trigger), describe and draw the output waveform. Please describe and draw the comparator output (Vo) by clearly labelling axes, threshold voltages and the saturation voltages in your sketch. Also show supporting calculations of the upper threshold point (UTP or V,"), lower threshold point (LTP or Vi) and the hysteresis voltage.
