One way to reduce noise in a system is to use averaging. To cut the noise in half, the number of samples in the average needs to be doubled. This gets slow, and taken to an extreme, the signal is long gone before enough averages can be taken. Thermal noise depends only on resistance, temperature, and bandwidth. There are no other variables.

Techniques such as twisted wire pairs and differential signaling (such as LVDS) can make circuitry tolerant of conducted noise without actually reducing the noise. A spectrum analyser or oscilloscope with fast fourier transform (FFT) capability can be very helpful in tracking down where noise is coming from by helping to show the nature of the noise and identify …

Wirewound resistors are the quietest of the three and come closest to ideal noise levels. Composition resistors are the noisiest because of their contact noise, which is aggravated by current. Otherwise composition resistors have the same noise as wirewound. You can reduce resistive noise by reducing the value of the resistors on your board.

Live Audio/Music: Band-stop filters are frequently used to eliminate or reduce feedback from amplification equipment by impeding a narrow frequency band (sometimes referred to as a “notch”) and thereby preventing the development of the feedback loop and resulting sound. High-pass filters are also frequently employed to clean up audio signals from non-bass instruments: …
