1、...电子与通信专业英语Digital Signal Processing（英文翻译）：豪班级：信工122学号：2012020217Digital Signal Processing1、Introduction Digital signal processing (DSP) is concerned with the representation of the signals by a sequence of numbers or symbols and the processing of these signals. Dig
2、ital signal processing and analog signal processing are subfields of signal processing. DSP includes subfields like audio and speech signal processing, sonar and radar signal processing, sensor array processing, spectral estimation, statistical signal processing, dig
3、ital image processing, signal processing for communications, biomedical signal processing, seismic data processing, etc. .......Since the goal of DSP is usually to measure or filter continuous real-world analog signals, the first step is usually to convert the signal
4、 from an analog to a digital form, by using an analog to digital converter. Often, the required output signal is another analog output signal, which requires a digital to analog converter. Even if this process is more complex than analog processing and has a discrete
5、 value range, the stability of digital signal processing thanks to error detection and correction and being less vulnerable to noise makes it advantageous over analog signal processing for many, though not all, applications. DSP algorithms have long been run on stand
6、ard computers, on specialized processors called digital signal processors (DSP)s, or on purpose-built hardware such as application-specific integrated circuit (ASICs). Today there are additional technologies used for digital signal processing including more powerful
7、general purpose microprocessors, field-programmable gate arrays (FPGAs), digital signal controllers (mostly for industrial applications such as motor control), and stream processors, among others. In DSP, engineers usually study digital signals in one of the followin
8、g domains: time domain (one-dimensional signals), spatial domain (multidimensional signals), frequency domain, autocorrelation doma
