Problem:
1. For the emitter-follower circuit shown in Figure, the BJT used is specified to have β values in the range\ of 50 to 200 (a distressing situation for the circuit designer).
For the two extreme values of β (β=50 and β=200), find
(a) IE, VE, and VB
(b) the input resistance Rin
(c) the voltage gain vo/vsig
