ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
A perturbation of the Earth's magnetic field, caused by solar disturbances, usually lasting for a brief period (several days) and characterized by large deviations from the usual value of at least one component of the field. Note: Magnetic storms can affect radio propagation because they disturb the ionosphere.
Industry:Telecommunications
A phase deviation from a specified value. 2. An unintentional deviation from the nominal phase value.
Industry:Telecommunications
A phase of the Development Process wherein the detailed specification of a Target of Evaluation is translated into actual hardware and software.
Industry:Telecommunications
A phase of the Development Process wherein the top level definition and design of a Target of Evaluation is refined and expanded to a level of detail that can be used as a basis for implementation.
Industry:Telecommunications
A phase-locked loop in which the reference signal, the controlled signal, or the controlling signal, or any combination of these, is in digital form.
Industry:Telecommunications
A phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. Note: In the usual implementation of a Costas loop, a local voltage-controlled oscillator provides quadrature outputs, one to each of two phase detectors, i.e., product detectors. The same phase of the input signal is also applied to both phase detectors and the output of each phase detector is passed through a low-pass filter. The outputs of these low-pass filters are inputs to another phase detector, the output of which passes through a loop filter before being used to control the voltage-controlled oscillator.
Industry:Telecommunications
A phenomenon, associated with FM reception, in which only the stronger of two signals at or near the same frequency will be demodulated. Note 1: The complete suppression of the weaker signal occurs at the receiver limiter, where it is treated as noise and rejected. Note 2: When both signals are nearly equal in strength, or are fading independently, the receiver may switch from one to the other. Synonym FM capture effect.
