Signal Processing

SIGNAL CLASSIFICATION

Signals can be either analog or digital, and 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.

Analog Signal Processing —for signals that have not been digitized, as in classical radio, telephone, radar, and television systems

Digital Signal Processing —for signals that have been digitized. Processing is done by digital circuits such as ASIC s, FPGA s, general-purpose Microprocessors or Computer s, or specialized Digital Signal Processor chips.

Statistical Signal Processing —analyzing and extracting information from signals based on their statistical properties

Audio Signal Processing —for electrical signals representing sound, such as music

Speech Signal Processing —for processing and interpreting spoken words

Image Processing —in digital cameras, computers, and various imaging systems

Video signal processing—for interpreting moving pictures

Array Processing —for processing signals from arrays of sensors
