My lecturer is going to be going over this question next week but I wanted to get a start on it in order to fully understand it. Here is what I think I know so far and any assistance would be great.
(a) (i) Zener Diode - voltage regulator
(ii) ?
(iii) See attached sketch
(b) (i) ?
(ii) C1 - Coupling capacitor to connect a.c. supply from input to base
C2 - Coupling capacitor to connect to output circuit
C3 - Decouples any a.c. variation on R4 allowing gain?
(iii) Av = - (R3/R4)
(iv) ?
