Digital signal processing (DSP) enables many technologies that are in widespread use including cellular telephones, wireless data networks, digital audio, digital video, speech coding, voice and video compression, etc. In data networking applications, DSP is used to reduce the effects of noise, interference, and signal distortion so that higher data rates can be achieved along with lower error rates. In compression applications, DSP is used to analyze and modify signals and thereby reduce the number of bytes required to store or transmit the signal. In audio and video equipment, DSP is used to enhance the perceived quality of the signal.

数字信号处理（DSP）使许多技术得到广泛应用，包括蜂窝电话、无线数据网络、数字音频、数字视频、语音编码、语音和视频压缩等。在数据网络应用中，DSP用于减少噪声、干扰和信号失真的影响，从而可以沿着更低的错误率来实现更高的数据速率。 在压缩应用中，DSP用于分析和修改信号，从而减少存储或传输信号所需的字节数。 在音频和视频设备中，DSP用于增强信号的感知质量。
