Bench Number 4 Question 1: Plot V o as a function of V in for the comparator circuit using the data from Part A. Plotting the output voltage as a function of the input voltage for the comparator:
out vs. V in -20 -15 -10 -5 0 5 10 15 20 0 1 2 3 4 5 6 7 8 9 V in [Volts] V out [Volts] Vout [Volts] Question 2: What are the changes to the V o waveform on the oscilloscope when you vary V ref from -6Volts to +6Volts in Part A? Explain what you observe. The changes to the V o waveform on the oscilloscope when you vary V ref from -6 Volts to +6 Volts are such that the as the reference voltage is increased to +6 Volts the output voltage waveform becomes more negative at the -15 Volts region. At threshold of +5 Volts for the reference voltage, the output voltage then becomes a -15 Volts throughout the response of the input voltage. As the reference voltage is then lowered from +3 Volts to -6 Volts the output voltage waveform becomes larger at the +15 Volts region. At the threshold of -5 Volts for the reference voltage, the voltage then becomes +15 Volts throughout the response of the input voltage. (See Figure 1 in Appendix for sample). Question 3: Write what you observe at V
