Signal compression is the use of various techniques to increase the quality or quantity of signal parameters transmitted through a given telecommunications channel. Types of signal compression include: * Bandwidth compression * Data compression * Dynamic range compression * Gain compression * Image compression * Lossy compression * One-way compression functionThis article includes a list of related items that share the same name (or similar names).
