an amplifier with a 1 MHz bandwidth and a 20 micro-V input signal. The input noise = 1 micro-V, output signal = 6.0 mV, and output noise = 1 mV. Find (a) SNR at the input Pin = Pn(in)= K(T)BW= 1.38*10-23(290)1MHz= 4*10-15W (b) SNR at the output (c) Noise figure NF= 10 log(400/36)= 10.458dB I know the answers are (a) 400 (b) 36. find the input power (Pin) to calculate the SNR for part a.
