Frequency response of the multirate multistage filter

`[`

returns the complex frequency response, `h`

,`f`

] = freqz(`sysobj`

,`n`

,`range`

)`h`

, of the multirate
multistage filter System object™ and the frequency vector `f`

at which
`h`

is computed. `n`

is the number of
frequency points, and `range`

is the frequency range over which
the response is computed.

For the sample rate converter object, the sample rate is the larger of
`InputSampleRate`

and
`OutputSampleRate`

.
