modification to a electronic system or signal. In audio applications, noise can be added to the audible signal, effecting the audio signal quality. Common design practices target eliminating or reducing noise sources to improve the overall system performance. Noise sources vary in audio converters but there are a few ways to optimize a design.

sb(τ)c(t−τ)dτ +z(t) = sb(t)+z(t) = X∞ k=−∞. I[k]gT(t−kT)+z(t). In order to limit the noise power in the demodulated signal, yb(t) is usually filtered with a filter gR(t). Thereby, gR(t) can be e.g. a lowpass filter or the optimum matched filter. The filtered received signal is rb(t) = …

http://123.physics.ucdavis.edu/week_5_files/filters/matched_filter.pdf
Noise is the unwanted electromagnetic energy that interferes with the ability of the receiver to detect the wanted signal. It may enter the receiver through the antenna along with the desired signal or it may be generated within the receiver. As discussed earlier, noise is generated by the thermal motion of the conduction
