102Modulation — For musical change of key, see Modulation (music). For other uses, see Modulation (disambiguation). Passband modulation v · d · e …
103Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port …
104Squeezed coherent state — In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value::Delta x Delta p =… …
105QAM — Modulation d amplitude en quadrature La modulation d amplitude en quadrature (en anglais, Quadrature Amplitude Modulation ou QAM) est une forme de modulation d une porteuse par modification de l amplitude de la porteuse elle même et d une onde en …
106Polar modulation — is analogous to quadrature modulation in the same way that polar coordinates are analogous to Cartesian coordinates. Quadrature modulation makes use of Cartesian coordinates, x and y . When considering quadrature modulation, the x axis is called… …
107All-pass filter — An all pass filter is an electronic filter that passes all frequencies equally, but changes the phase relationship between various frequencies. It does this by varying its propagation delay with frequency. Generally, the filter is described by… …

Pour demander sa remise en service, faire une requête sur WP:RBOT Cette page recense les articles relatifs aux mathématiques, qui sont liés aux portails de mathématiques, géométrie ou… …
109Carrier recovery — A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal s carrier wave and the receiver s local oscillator for the purpose of coherent demodulation. Example of QPSK… …
