What is impulse response in image processing?
In signal processing and control theory, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse (δ(t)). More generally, an impulse response is the reaction of any dynamic system in response to some external change.
What is the impulse response of the system?
The impulse response of a system is the output of the system in response to a unit impulse input signal. This lesson introduces you convolution, which expresses the output of an LTI system as a function of its input and impulse response.
What is impulse response in LTI system?
The impulse response for an LTI system is the output, y ( t ) y(t) y(t), when the input is the unit impulse signal, σ ( t ) \sigma(t) σ(t). In other words, when x ( t ) = σ ( t ) , h ( t ) = y ( t ) .
