An integrated circuit, usually in the form of a microprocessor, designed specifically for high-speed signal processing (i.e., data manipulation) tasks, typically in real time, and built into another device. In a typical telecommunications application, an analog-to-digital converter (ADC) samples an analog signal and converts it into digital format. A DSP then encodes the signal into pulse code modulation (PCM) format, employing an appropriate algorithm such as A-law or mu-law to produce a standard output like a DS-0 channel. A DSP might then filter noise and remove interference from the signal, and transcode, compress, and perhaps encrypt the signal prior to placing it on a carrier of an electrically based digital circuit for transmission. A matching DSP reverses the process on the receiving side of the communication, sending the signal to a digital-to-analog converter (ADC) for decoding back into real world analog form, perhaps with improved clarity, a shifted frequency, or demodulated. DSPs are used in audio, communications, image manipulation, and video applications. DSPs are built into cellular telephones, fax machines, modems, and many other devices. See also ADC, A-law, analog, carrier, channel, codec, compression, DAC, digital, DS-0, encode, encryption, interference, mu-law, noise, PCM, and transcode.
