Given below is a center tapped transformer with the each secondary coil set rendering 12 V p-p. Draw the voltage output pattern across the resistor R1.

In the lab you have verified or will be verifying shortly that an NPN transistor operates differently than a diode that is connected to a negative dc potential (Vbias_dc = -15 V) as shown below. An ac signal input is applied as shown. For the circuit given below, show analytically that the output signal, Vout has a dc off-set and is also attenuated in comparison to the input.
