41High-energy radio-frequency weapons — (HERF) or High Power Radio Frequency weapons (HPRF) are weapons that use high intensity radio waves to disrupt electronics. They are a type of directed energy weapon. They operate similarly to electromagnetic pulse (EMP) devices, by inducing… …
42Variable-frequency drive — A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.cite book | first=Sylvester J. |… …
43Global Frequency — est une série de comics en 12 épisodes créée par Warren Ellis, qui scénarise tous les épisodes, et publiée par Wildstorm. Sa particularité est d avoir une équipe artistique différente par épisode, qui constitue une histoire compréhensible par… …
44Configural frequency analysis — (CFA) (Lienert, 1969) is a method of exploratory data analysis. The goal of a configural frequency analysis is to detect patterns in the data that occur significantly more (such patterns are called Types) or significantly less often (such… …
45Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …

47Reconstruction from zero crossings — The problem of reconstruction from zero crossings can be stated as: given the zero crossings of a continuous signal, is it possible to reconstruct the signal (to within a constant factor)? Worded differently, what are the conditions under which a …
48Carrier frequency — is a term used to designate: * The nominal frequency of a carrier wave * The center frequency of a frequency modulation signal * The frequency of the unmodulated electrical wave at the output of an amplitude modulated (AM), frequency modulated… …
49Self-resonant frequency — In electronics, capacitors and inductors have parasitic inductance and capacitance, respectively. Since a capacitor and inductor in series creates an oscillating circuit, all capacitors and inductors will oscillate when stimulated with a step… …
50Constant amplitude zero autocorrelation waveform — A Constant Amplitude Zero AutoCorrelation waveform (abbreviated CAZAC) is a periodic complex valued signal with modulus one and out of phase periodic (cyclic) autocorrelation equal to zero. CAZAC sequences find application in wireless… …
