An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.
Audio compression may refer to: Audio compression (data) , a type of lossy or lossless compression in which the amount of data in a recorded waveform is reduced to differing extents for transmission respectively with or without some loss of quality, used in CD and MP3 encoding, Internet radio, and the like
The basis for digital video cameras is metal–oxide–semiconductor (MOS) image sensors. [1] The first practical semiconductor image sensor was the charge-coupled device (CCD), invented in 1969 [2] by Willard S. Boyle, who won a Nobel Prize for his work in physics. [3]
