Impulse response

Syntax

[h,t] = impz(H)
[h,t] = impz(H,Name,Value)
impz(H)

Description

[h,t] = impz(H) returns the impulse response h, and the corresponding time points t at which the impulse response ofH is computed.

[h,t] = impz(H,Name,Value) returns the impulse response h, and the corresponding time pointst , with additional options specified by one or more Name, Value pair arguments.

impz(H) uses FVTool to plot the impulse response of the filter System object™ H.

    Note:   You can use impz for both real and complex filters. When you omit the output arguments, impz plots only the real part of the impulse response.
