Part 1: op amp comparator Construct the following open-circuit (no feedback) op amp comparator circuit (positive comparator). V2 15 دن Vout Vin V1 V3 Vref LM741/NS 15 SINECO 50.1K) .tran 0 50m 0 0.1m step param Vr 0 51 .inc C:\Program Files\LTC LTspiceXVII\lib sub\LM741.MOD Record: Set the AC input Vin at the op amp's positive signal input terminal as a sine wave, 10Vpp, 0.1kHz. Set the DC input Vref at the op amp's negative signal input a IV reference voltage. Use a scope to record and overlay both Vin and Vout waveforms. Modify the reference voltage Vref to values to -5V, -3V, -1V, OV, 3V, and 5V. Use a scope to record and overlay both Vin and Vout waveforms. Explain: how the reference voltage Vref affects the output voltage waveforms. Part 1 data form How does the reference voltage Vref affect the output voltage waveforms?
