The time delay prompt procedures are different from SLP and MTL procedures because instead of removing prompts by progressing through a hierarchy, prompts are removed by delaying them in time. The progressive time delay procedure was developed first, [12] and the constant time delay procedure was developed as a more parsimonious procedure for ...
The signal delay of a wire or other circuit, measured as group delay or phase delay or the effective propagation delay of a digital transition, may be dominated by resistive-capacitive effects, depending on the distance and other parameters, or may alternatively be dominated by inductive, wave, and speed of light effects in other realms.
First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.
An implementation of a constant-time algorithm is sometimes called a timing-safe implementation. [2] Consider an implementation in which every call to a subroutine always returns in exactly x seconds, where x is the maximum time it ever takes to execute that routine on every possible authorized input.
The bridged-T delay equaliser is an electrical all-pass filter circuit utilising bridged-T topology whose purpose is to insert an (ideally) constant delay at all frequencies in the signal path. It is a class of image filter .
A time-variant system is a system whose output response depends on moment of observation as well as moment of input signal application. [1] In other words, a time delay or time advance of input not only shifts the output signal in time but also changes other parameters and behavior.
The FO4 time for a technology is five times its RC time constant τ; therefore 5·τ = FO4. [2] Some examples of high-frequency CPUs with long pipeline and low stage delay: IBM Power6 has design with cycle delay of 13 FO4; [3] clock period of Intel's Pentium 4 at 3.4 GHz is estimated as 16.3 FO4. [4]
Coherence time is actually a statistical measure of the time duration over which the channel impulse response is essentially invariant, and quantifies the similarity of the channel response at different times. In other words, coherence time is the time duration over which two received signals have a strong potential for amplitude correlation.
