Detailed Description
Performs an 8-tap FIR filter with a multi-sample delay between taps.
The delay must be an integer multiple of the sampling period.
Member Function Documentation
◆ Refresh()
|
overridevirtual |
Evaluates a filter graph node.
This version does not support using Vulkan acceleration and should be considered deprecated. It will be removed in the indefinite future once all filters have been converted to the new API.
Reimplemented from Filter.
◆ ValidateChannel()
|
overridevirtual |
Reimplemented from FlowGraphNode.
The documentation for this class was generated from the following files:
- lib/scopeprotocols/TappedDelayLineFilter.h
- lib/scopeprotocols/TappedDelayLineFilter.cpp
