The item visible at the POSIX. 6/D13. 1 interface that is used for associating labeling information with object data. This information is not related to mandatory access control.
Industry:Telecommunications
The irradiance of an electromagnetic wave under specified conditions. Note: Field intensity is usually expressed in watts per square meter.
Industry:Telecommunications
The invocation of a function a security facility by another security facility.
Industry:Telecommunications
The inverse of a scrambler. Note: The descrambler output is a signal restored to the state that it had when it entered the associated scrambler, provided that no errors have occurred.
Industry:Telecommunications
The invariability of a specified property of a substance, device, or apparatus with time, or under the influence of typically extrinsic factors.
Industry:Telecommunications
The interval required for a system or circuit to change a specified fraction from one state or condition to another. Note 1: The time constant is used in the expression where A (t) is the value of the state at time t, A (0) is the value of the state at time t = 0, a is the time constant, and t is the time that has elapsed from the start of the exponential decay. Note 2: When t = a, A (t) /A (0) = 1/e, or approximately 0. 37, and the system has changed about 63% toward its new value in one time constant. A system is considered to have changed its state after the elapse of three time constants, which corresponds to a 95% change in state. For example, if an electrical capacitor, having a capacitance of C farads, is discharged through a resistor, having a resistance of R ohms, the capacitor will be approximately 95% discharged after the elapse of 3RC seconds. Note 3: Time constants are expressed in seconds, such as 3. 5 × 10-6 seconds, i.e., 3. 5 s.
Industry:Telecommunications
The interval from the instant a transmitter is keyed-on to the instant the transmitted radio frequency (rf) signal amplitude has increased to a specified level, usually 90% of its key-on steady-state value. Note: The transmitter attack-time delay excludes the time required for automatic antenna tuning.
Industry:Telecommunications
The interval from the instant a transmitter is keyed-off to the instant the transmitted radio frequency (rf) signal amplitude has decreased to a specified level, usually 10% of its key-on steady-state value.
Industry:Telecommunications
The interval between two successive time code states. Note: Time code resolution is determined by the most rapidly changing symbol position within the time code. For example, for a digital clock that displays hours and minutes, the time code resolution would be 1 minute.
