14Signal box — A signal box or signal cabin is a building from which railway signals and points are controlled. The term signal cabin is used in Ireland, parts of Scotland and in Australia while in North America, the term interlocking tower predominates.… …
15Signal 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,… …
16Signal compression — In telecommunication, the term signal compression has the following meanings: In analog (usually audio) systems, reduction of the dynamic range of a signal by controlling it as a function of the inverse relationship of its instantaneous value… …
