51Non Return to Zero — und Non Return to Zero Invert, abgekürzt NRZ und als NRZI, sind die einfachsten Leitungscodes für binäre Signale. Im Gegensatz zum RZ Code bestehen die beiden binären Symbole aus konstanten Leitungszuständen (meist Spannungen). Von Nachteil ist,… …
52critical frequency — i. The frequency at which a critical angle becomes zero. The highest frequency at which vertical reflection is possible. ii. The frequency corresponding to the resonance frequency of a blade, control surface, or other vibrating or moving… …
53Alternate-Phase Return-to-Zero (APRZ) — is an optical signal format. In APRZ the field intensity drops to zero between consecutive bits (RZ), and the field phase alternates between neighbouring bits (AP), so that if the phase of the signal is, for example, 0 in even bits (bit number 2… …
54Multidelay block frequency domain adaptive filter — The Multidelay block frequency domain adaptive filter (MDF) algorithm is a block based frequency domain implementation of the (normalised) Least mean squares filter (LMS) algorithm. Contents 1 Introduction 2 Variable definitions 3 Algorithm… …
55Finite-difference frequency-domain — The finite difference frequency domain (FDFD) is a numerical solution for problems usually in electromagnetism. The method is, of course, based on finite difference approximations of the derivative operators in the differential equation being… …

58Nyquist–Shannon sampling theorem — Fig.1: Hypothetical spectrum of a bandlimited signal as a function of frequency The Nyquist–Shannon sampling theorem, after Harry Nyquist and Claude Shannon, is a fundamental result in the field of information theory, in particular… …
59Sampling (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 …
60Baseband — In signal processing, baseband is an adjective that describes signals and systems whose range of frequencies is measured from zero to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies… …
