Unbalanced signals use fewer wires.C. Balanced signals use ground for one of the two wires.D. Unbalanced signals take advantage of the common-mode rejection capability of op amps.Two correct possible answers.arrow_forward- V2 15Vdo 3 U1A R1 2 1k V- LM324 1k V3 15Vde | VOFF = 0 VAMPL = 1 FREQ = 2k AC = 0 0. R2 Figure 4. Operational amplifier circuit. What frequency does the output voltage (across R3) have? What is the amplitude of the output voltage? From the output waveform and the input waveform, determine the gain of the op-amp circuit. Does this match with what you predicted? How could you change this circuit so that the output voltage would be nearly the same as the input voltage? What purpose would that serve? Can you modify the existing circuit and verify this experimentally? What is the phase difference between the output and input voltage? Derive the transfer function for the output-input relationship for the operational amplifier. How would the gain and the output change if a capacitor were in the feedback path instead of a resistor?

My question is, since current flowing through R5, IR5=0, is the current flowing through R4 = 0 as well? And for this circuit, is the current flowing through the short circuit = infinity?arrow_forward
