Signal-to-noise ratio

Signal-to-noise ratio abbreviated SNR or S/N is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.SNR is defined as the ratio of signal power to the noise power, often expressed in decibels.

Radio noise

The vertical axis is in decibels above the thermal noise floor. It can be seen that as frequency drops atmospheric noise dominates other sources. In radio reception, radio noise is unwanted random radio frequency electrical signals, fluctuating voltages, always present in a radio receiver in addition to the desired radio signal.

Noise electronics

Noise types. Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature see fluctuation-dissipation theorem , while other types depend mostly on device type such as shot noise, which needs a steep potential barrier or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f .

Noise signal processing

Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory, namely the Nyquist–Shannon sampling theorem.

Spectral leakage

That perspective might help to interpret the different noise-floor levels between the two graphs in the figure on the right. Both spectra were made from the same data set with the same noise power. But the bins in the bottom graph each responded more strongly than the bins in the top graph. The exact amount of the difference is given by the ENBW difference of the two window functions.

Noise, vibration, and harshness

Structure-borne noise is attenuated by isolation, while airborne noise is reduced by absorption or through the use of barrier materials. Vibrations are sensed at the steering wheel, the seat, armrests, or the floor and pedals. Some problems are sensed visually - such as the vibration of the rear-view mirror or header rail on open-topped cars.

Adding some dithering noise to the input signal can actually improve the final result because the dither noise allows oversampling to work to improve resolution. In many practical applications, a small increase in noise is well worth a substantial increase in measurement resolution. In practice, the dithering noise can often be placed outside the frequency range of interest to the measurement .
