9-1: Basic Principles of Signal Reproduction
Another factor that affects the sensitivity of a receiver is the signal-to-noise (S/N) ratio (SNR).
One method of expressing the sensitivity of a receiver is to establish the minimum discernible signal (MDS).
The MDS is the input signal level that is approximately equal to the average internally generated noise value.
This noise value is called the noise floor of the receiver.
MDS is the amount of signal that would produce the same audio power output as the noise floor signal.
