Italicized Questions: 1.) What are the values of the resistors and supply voltages? Measure the dc voltages at points A, B, and C. A = – 0.687 V B = 5.73 V C = 5.33 V What relationship do the waveforms at B and C have to the input? The waveform at B has increased in amplitude (about 33 times bigger) and is inverted compared to the input.
