Signal Processing

SIGNAL CLASSIFICATION

Signals can be either analog, in which case the signal varies continuously according to the information, or digital, in which case the signal varies according to a series of discrete values representing the information. Signals may come from various sources.

There are various sorts of signal processing, depending on the nature of the signal, as in the following examples.

For analog signals, signal processing may involve the amplification and filtering of audio signals for audio equipment or the modulation and demodulation of signals for telecommunications. For digital signals, signal processing may involve the compression, error checking and error detection of digital signals.

Digital Signal Processing - for signals that have been digitized. Processing is done by digital circuits (possibly in ASIC s or in FPGA s), with general purpose Microprocessors or Computer s, or with specialized Digital Signal Processor s designed specifically for the purpose of DSP.

Analog Signal Processing - for signals that have not been digitized

Audio Signal Processing - for electrical signals representing sound

Speech signal processing - for interpreting spoken words

Video signal processing - for interpreting moving pictures

Array Processing
