aliasing frequencies
71Electronic engineering — is a discipline dealing with the behavior and effects of electrons (as in electron tubes and transistors) and with electronic devices, systems, or equipment.The term now also covers a large part of electrical engineering degree courses as studied …
72Numerically-controlled oscillator — A numerically controlled oscillator (NCO) or digitally controlled oscillator (DCO) is an electronic system for synthesizing a range of frequencies from a fixed timebase. The name is an analogy with voltage controlled oscillator . Note: the term… …
73Root locus — In control theory, the root locus is the locus of the poles and zeros of a transfer function as the system gain K is varied on some interval. The root locus is a useful tool for analyzing single input single output (SISO) linear dynamic systems.… …
74Signal reconstruction — In signal processing, reconstruction usually means the determination of an original continuous signal from a sequence of equally spaced samples.This article takes a generalized abstract mathematical approach to signal sampling and reconstruction …
75PXL-2000 — The Fisher Price PXL2000 (also known as the PixelVision by Fisher Price, and the KiddieCorder by some of its fans) was a toy black and white camcorder produced in 1987 that used an ordinary compact audio cassette as its recording medium. The… …
76Stroboscope — A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow moving, or stationary. The principle is used for the study of rotating, reciprocating, oscillating or vibrating objects. Machine… …
77Linn LM-1 — The LM 1 Drum Computer, manufactured by Linn Electronics Inc., was the first drum machine to utilize digital samples of acoustic drums. Conceived and designed by Roger Linn, it was also one of the first programmable drum machines. It was… …
78Color filter array — The Bayer color filter mosaic. Each two by two submosaic contains 2 green, 1 blue and 1 red filter, each covering one pixel sensor. In photography, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed …
79Bucket Brigade Device — A Bucket Brigade is an analogue delay line, developed in 1969 by F. Sangster and K. Teer of the Philips Research Labs. It consists of a series of capacitances C0 to Cn. The stored analogue signal is moved along the line of capacitors one step at… …
80Relations between Fourier transforms and Fourier series — In the mathematical field of harmonic analysis, the continuous Fourier transform has very precise relations with Fourier series. It is also closely related to the discrete time Fourier transform (DTFT) and the discrete Fourier transform (DFT).… …
