Any process by which a specified characteristic (usually amplitude) of the output of a device is prevented from exceeding a predetermined value. Note 1: Hard limiting ("clipping") is a limiting action in which there is (a) over the permitted dynamic range, negligible variation in the expected characteristic of the output signal, and (b) a steady-state signal, at the maximum permitted level, for the duration of each period when the output would otherwise be required to exceed the permitted dynamic range in order to correspond to the transfer function of the device. Note 2: Soft limiting is limiting in which the transfer function of a device is a function of its instantaneous or integrated output level. The output waveform is therefore distorted, but not clipped.

Industry:Telecommunications
Any radiocommunication involving the use of one or more space stations or the use of one or more reflecting satellites or other objects in space.
Industry:Telecommunications
Any radiocommunication other than space radiocommunication or radio astronomy.
Industry:Telecommunications
Any radiocommunication service used permanently or temporarily for the safeguarding of human life and property.
Industry:Telecommunications
Any service provided by a telecommunication provider. 2. A specified set of user-information transfer capabilities provided to a group of users by a telecommunications system. Note: The telecommunications service user is responsible for the information content of the message. The telecommunications service provider has the responsibility for the acceptance, transmission, and delivery of the message.

Industry:Telecommunications
Any shifting (often quite rapid,) from whatever cause, in the phase of a signal. Note 1: The shifting in phase may appear to be random, cyclic, or both. Note 2: The phase departure in phase perturbation usually is larger, but less rapid, than that of phase jitter. Note 3: Phase perturbation may be expressed in degrees, with any cyclic component expressed in hertz.
Industry:Telecommunications
Any signal that tends to produce degradation in the operation of equipment or systems.
Industry:Telecommunications
Any specific and uniquely identifiable physical human characteristic, e. G. , of the retina, iris, acoustic spectrum of the voice (i.e., voiceprint,) fingerprint (s,) handwriting, pattern of finger lengths, etc. , that may be used to validate the identity of an individual. Note: Biometrics provide a highly secure means of identification, for purposes of security involving, e. G. , Internet communications and cryptosystems.
