Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… … Wikipedia
Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the … Wikipedia
Sampling rate — Analog signal and resulting sampled signal. The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time domain signals, it… … Wikipedia
Analog-to-digital converter — An analog to digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital to analog converter… … Wikipedia
Analog multiplier — In electronics, an analog multiplier is a device which takes two analog signals and produces an output which is their product. Such circuits can be used to implement related functions such as squares (apply same signal to both inputs), and square … Wikipedia
Analog high-definition television system — Historically the term high definition television was first used to refer to television standards developed in the 1930s to replace early experimental systems with as few as 12 lines. Not so long afterwards John Logie Baird, Philo T. Farnsworth… … Wikipedia
