22Pulse-code modulation — PCM redirects here. For other uses, see PCM (disambiguation). Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu ray, Compact Disc and …
23information theory — the mathematical theory concerned with the content, transmission, storage, and retrieval of information, usually in the form of messages or data, and esp. by means of computers. [1945 50] * * * ▪ mathematics Introduction a mathematical… …
24Autocorrelation — is a mathematical tool for finding repeating patterns, such as the presence of a periodic signal which has been buried under noise, or identifying the missing fundamental frequency in a signal implied by its harmonic frequencies. It is used… …
25Nyquist frequency — Not to be confused with Nyquist rate. Frequencies above ƒs/2 (the Nyquist frequency) have an alias below ƒs/2, whose value is given by this graph. ƒs/2 is also called folding frequency, because of the symmetry between 0 and ƒs. The Nyquist… …
26Digital processing — is the process of altering digital data in any form.The most common situations where digital processing is involved are computer graphics and digital audio processing. The two are related regarding both the problems encountered and the solutions… …
27Programmable logic controller — A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. PLCs are used in many different industries and machines… …
28Estimation theory — is a branch of statistics and signal processing that deals with estimating the values of parameters based on measured/empirical data. The parameters describe an underlying physical setting in such a way that the value of the parameters affects… …
29Variable fractional delay filter — Introduction= One important advantage of the variable digital filter is that the frequency characteristics, including the magnitude response and the phase response are tunable without re implementation of the filter. Variable fractional delay… …
