signal processing

Waveform mathematical manipulation

Signal processing is the analysis, modification, and synthesis of signals—representations of information such as sound, images, or data streams.

Engineers filter noise from audio recordings, compress video for streaming, or extract patterns from sensor data.

The field underlies technologies from smartphones to medical imaging: The hearing aid uses digital signal processing to amplify speech while reducing background noise.
