Response to the following problem:
For the emitter-follower circuit shown in Fig., 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
