  2. Propagation delay - Wikipedia

    en.wikipedia.org/wiki/Propagation_delay

    It is the time between the gate input becoming stable and the gate output becoming stable. Manufacturers often refer to the time from the input changing to 50% of its final input level, to the output reaching 50% of its final output level; this may depend on the direction of the level change, in which case separate fall and rise delays t PHL ...

  3. Latency (engineering) - Wikipedia

    en.wikipedia.org/wiki/Latency_(engineering)

    Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.

  4. Time delay neural network - Wikipedia

    en.wikipedia.org/wiki/Time_delay_neural_network

    The precise architecture of TDNNs (time-delays, number of layers) is mostly determined by the designer depending on the classification problem and the most useful context sizes. The delays or context windows are chosen specific to each application. Work has also been done to create adaptable time-delay TDNNs [10] where this manual tuning is ...

  5. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    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.

  6. Transfer function - Wikipedia

    en.wikipedia.org/wiki/Transfer_function

    The transfer function of a two-port electronic circuit, such as an amplifier, might be a two-dimensional graph of the scalar voltage at the output as a function of the scalar voltage applied to the input; the transfer function of an electromechanical actuator might be the mechanical displacement of the movable arm as a function of electric ...

  7. Linear time-invariant system - Wikipedia

    en.wikipedia.org/wiki/Linear_time-invariant_system

    The defining properties of any LTI system are linearity and time invariance.. Linearity means that the relationship between the input () and the output (), both being regarded as functions, is a linear mapping: If is a constant then the system output to () is (); if ′ is a further input with system output ′ then the output of the system to () + ′ is () + ′ (), this applying for all ...

  8. Time-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Time-to-digital_converter

    In electronic instrumentation and signal processing, a time-to-digital converter (TDC) or time digitizer (TD) is a device for recognizing events and providing a digital representation of the time they occurred. For example, a TDC might output the time of arrival for each incoming pulse. Some applications wish to measure the time interval ...

  9. Time derivative - Wikipedia

    en.wikipedia.org/wiki/Time_derivative

    The growth rate of output is the time derivative of the flow of output divided by output itself. The growth rate of the labor force is the time derivative of the labor force divided by the labor force itself. And sometimes there appears a time derivative of a variable which, unlike the examples above, is not measured in units of currency:
