  2. Impulse response - Wikipedia

    en.wikipedia.org/wiki/Impulse_response

    The impulse response of a linear transformation is the image of Dirac's delta function under the transformation, analogous to the fundamental solution of a partial differential operator. It is usually easier to analyze systems using transfer functions as opposed to impulse responses. The transfer function is the Laplace transform of the impulse ...

  3. Dirac delta function - Wikipedia

    en.wikipedia.org/wiki/Dirac_delta_function

    The impulse response can be computed to any desired degree of accuracy by choosing a suitable approximation for δ, and once it is known, it characterizes the system completely. See LTI system theory § Impulse response and convolution. The inverse Fourier transform of the tempered distribution f(ξ) = 1 is the delta function.

  4. RL circuit - Wikipedia

    en.wikipedia.org/wiki/RL_circuit

    The impulse response for each voltage is the inverse Laplace transform of the corresponding transfer function. It represents the response of the circuit to an input voltage consisting of an impulse or Dirac delta function. The impulse response for the inductor voltage is

  5. RC circuit - Wikipedia

    en.wikipedia.org/wiki/RC_circuit

    The impulse response of a series RC circuit. The impulse response for each voltage is the inverse Laplace transform of the corresponding transfer function. It represents the response of the circuit to an input voltage consisting of an impulse or Dirac delta function. The impulse response for the capacitor voltage is

  6. Finite impulse response - Wikipedia

    en.wikipedia.org/wiki/Finite_impulse_response

    The impulse response (that is, the output in response to a Kronecker delta input) of an N th-order discrete-time FIR filter lasts exactly + samples (from first nonzero element through last nonzero element) before it then settles to zero.

  7. Infinite impulse response - Wikipedia

    en.wikipedia.org/wiki/Infinite_impulse_response

    Infinite impulse response (IIR) is a property applying to many linear time-invariant systems that are distinguished by having an impulse response that does not become exactly zero past a certain point but continues indefinitely.

  8. Duhamel's integral - Wikipedia

    en.wikipedia.org/wiki/Duhamel's_integral

    If a system initially rests at its equilibrium position, from where it is acted upon by a unit-impulse at the instance t=0, i.e., p(t) in the equation above is a Dirac delta function δ(t), () = | = =, then by solving the differential equation one can get a fundamental solution (known as a unit-impulse response function)

  9. Linear system - Wikipedia

    en.wikipedia.org/wiki/Linear_system

    The time-varying impulse response h(t 2, t 1) of a linear system is defined as the response of the system at time t = t 2 to a single impulse applied at time t = t 1.
