Overview¶

Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurement

Applications¶

Audio signal processing– for electrical signals representing sound, such as speech or music
Image processing – in digital cameras, computers and various imaging systems
Video processing – for interpreting moving pictures
Wireless communication – waveform generations, demodulation, filtering, equalization
Control systems
Array processing – for processing signals from arrays of sensors
Process control – a variety of signals are used, including the industry standard 4-20 mA current loop
