In digital sound systems, the frequency and amplitude of sound waves are measured and converted into electrical impulses. The pulses are encoded as a series of numbers or digits, in binary form. The binary code recognizes only two digits, 0 and 1, which correspond to "no pulse" and "pulse".
When playing a digital recording, the signals are decoded by translating them to the usual analog signals that activate and excite the loudspeakers.
A digital system has to store a lot of information about the sounds it records and it does so in the form of digits or bits. Since there are too many bits, the compact disc is used to store them.
