Signal Processing

Signal processing

A signal processing is a method to improve the sound quality before the final output. This process is in use since 1920s and is popularly used in radio broadcasting to clean up the sound distortion and to improve the quality of audio signal before transmitting. Signal processing can be further classified in two categories – analog processing and digital processing. Moreover, signal processing is widely applied to clean up the background sound and to produce a clear sound by boosting the signal volume.
