ECET 310 Week 2 Assignment Homework 2_1
Computer Science - General Computer Science
1. Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz, find
(a) therms input noise levels
(b) the audio output levels
the rms output noise levels
2. We have an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input mV, output mV, and output mV.
Find
(a) SNR at the input
(b) SNR at the output
Noise figure
3. An FM receiver has at the input and at the output.
Calculate the receiver’s noise figure in dB’s.
