In
a differential amplifier, the noninverting input is 3cos(600t +
45°) mV and the inverting input is 4cos (600t - 45°) mV. The
ooutput is vo = 3cos (600t - 45°) + 4.004cos (600t - 45°) V.
The CMRR is of? The unit must be in dB.
Is vo= 3cos(600t + 45 ◦ ) + 4.004cos(600t - 45◦) V
instead of:
vo = 3cos(600t - 45 ◦ ) + 4.004cos(600t - 45 ◦ ) V
