Digital signal processor

A digital signal processor (DSP) is a type of computer chip that is used to process digital signals. Digital signals are signals that have been converted from analog signals (like sound and video) into digital information (like numbers and letters). The DSP takes this digital information and uses it to process audio or video, like adding reverb or changing the volume of a track. It can also process signals from sensors to help robots and drones make sense of their environment, like detecting obstacles or recognizing faces. Think of a DSP like a very powerful calculator that uses digital information to make changes to sound, video, or sensor data.
