Frequency specified response function

[nwittler]

Describe the missing feature

Frequency specified response function.

Describe the solution you'd like

Another response function device that is parametrized in frequency space (as opposed to the time-domain functions we already have).

Describe alternatives you've considered

No need.

Additional context

The function should be sampled in frequency space at the resolution required by the input signal. @shaimach , feel free to add more context/requirements.
