Generic Filterbank

A filter bank with generic taps.

This block takes in a vector of N complex inputs, passes them through N FIR filters, and outputs a vector of N complex outputs.

The only advantage of using this block over N individual FIR filter blocks is that it places less of a load on the scheduler.

The number of filters cannot be changed dynamically, however filters can be deactivated (i.e. no processing is done for them) by passing a vector of filter taps containing all zeros to them. In this case their entry in the output vector is a zero.

Parameters

(R): Run-time adjustable

Taps(list of lists) (R)

(vector of vector of floats / list of list of floats) Populates the filters.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
