Critical band — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Psychophysiologically, beating and auditory roughness sensations can be linked to the inability… … Wikipedia
Critical bands — The term critical band, introduced by Harvey Fletcher in the 1940s, referred to the frequency bandwidth of the then loosely defined auditory filter. Since Georg von Békésy’s studies (1960), the term also refers literally to the specific area on… … Wikipedia
Signal to noise ratio (image processing) — The Signal to Noise Ratio (SNR) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) and therefore apply the 20 log rule to the pure SNR ratio. In turn,… … Wikipedia
Radar — For other uses, see Radar (disambiguation). A long range radar antenna, known as ALTAIR, used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll … Wikipedia
Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… … Wikipedia
SQNR — The acronym SQNR (standing for Signal to Quantization Noise Ratio) is widely used in communication systems analysis, particularly in PCM (pulse code modulation) schemes.The SQNR formula is derived from the general SNR (Signal to Noise Ratio)… … Wikipedia
Decibel — This article is about the ratio of measures. For sound or acoustic level, see Sound pressure. For other uses, see Decibel (disambiguation). Attenuation chart of an RG 6 Coaxial cable, measured in decibels per 100 feet of cable The decibel (dB) is … Wikipedia
Audio system measurements — are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative… … Wikipedia
Audio bit depth — In digital audio, bit depth describes the number of bits of information recorded for each sample. Bit depth directly corresponds to the resolution of each sample in a set of digital audio data. Common examples of bit depth include CD audio, which … Wikipedia
Phase-Comparison Monopulse — Phase interferometry describes a technique that can be used in radar and direction finding applications to accurately estimate the direction of arrival of a signal from the phase difference of the signal measured on two (or more) separated… … Wikipedia
