Please see the attachment for circuit diagram, where

R1 = 91k ohms
R2 = 20k ohms
Re = 1k ohms
Rc = 5k ohms.

Connect two identical amplifier stages like the one above in cascade (one after the another). What are the voltage gain and input and output impedances of the combination? Assume that the circuit is driven from a 50 Ohm source resistance generator. What is the (rms) voltage noise (referred to the input of the first stage) for a bandwidth from 1 kHz to 11 kHz frequency? What is the total noise referred to the output (of the second stage)? Your calculation of noise should be accurate to about 10%.
