As shown in the figure below, if there is no resistor R3, then when the voltage at point A (i.e. Vin) is greater than (VT1+Vbe), the PNP will be turned on. If resistor R3 is added now, the voltage on
The input and output voltages of the first amplifier are the same. The voltage is not amplified, nor is it operated. What is its function? I don't understand the second amplifier at all. Why is an amp
