Companding - Wikipedia
网页In telecommunications and signal processing, companding (occasionally called compansion) is a method of mitigating the detrimental effects of a channel with limited dynamic range. The name is a portmanteau of the words compressing and expanding, which are the functions of a compander at the transmitting and receiving ends, respectively.
Companding - Glossary
网页2023年10月16日 · Companding is an audio processing technique used to optimize the dynamic range of analog signals. It is utilized in various real-world applications to improve the quality and efficiency of audio transmission and storage. Here are three real-world examples of Companding technology:
What is Companding? - Definition from Techopedia
网页2011年9月19日 · What Does Companding Mean? Companding refers to a technique for compressing and then expanding (or decompressing) an analog or digital signal. It is a combination of the words “compressing” and “expanding.”
Companding: Logarithmic Laws, Implementation, and Consequences
网页2017年10月30日 · Companding is a portmanteau for a “compressing-expanding” mechanism. It compresses the signals before transmitting on a band-limited channel and expands them when received. During compression, an analog signal is quantized to create a digital signal using unequal steps in order to amplify the …
Companding - Vocab, Definition, and Must Know Facts - Fiveable
网页Companding is a signal processing technique that combines compression and expansion to reduce the dynamic range of a signal, making it easier to transmit and store. This method improves the efficiency of sampling and quantization by minimizing the effects of quantization noise and preserving the quality of the audio signal, especially for ...
What is Companding? - Webopedia
网页Companding is formed from the words compressing and expanding. It is a PCM compression technique where analog signal values are rounded on a non-linear scale. The data is compressed before sent and then expanded at the receiving end using the same non-linear scale. Companding reduces the noise and crosstalk levels at the receiver.
