Worksheet No. 7


No. 1 (circuit above) Calculate the capacitance of C1, to design a proper working bypass capacitor for the load RL. Frequency range: 20 - 20000 Hz

No. 2 (circuit below)

a) Draw the dc equivalent circuit.
b) Calculate the following dc values: IC, VCE
c) Draw the ac equivalent circuit.
d) Calculate the ac emitter resistance (re) and the ac collector resistance (rc).
e) What is the voltage gain AV?
f) What happens to the voltage gain if the supply voltage doubles?
