A Discussion On Amplifiers, Voltage, Signal-To-Noise Ratio
Please see attachment for diagram.
a) Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV.
b) If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifier.
