Easier in Digital
Once a signal has been reduced to numbers, its components can be isolated, analyzed and rearranged more easily than in analog form. DSP is used in many fields, including biomedicine, sonar, radar, seismology, audio, speech and music processing, imaging and communications. It is also used to create the concert hall and surround sound effects in stereo and home theater equipment. See DSP chip.
