* \brief Filter-Delay Combination Block.
41
* \ingroup filter_blk
42
*
43
* The block takes one or two float stream and outputs a complex
44
* stream.
45
*
46
* If only one float stream is input, the real output is a
47
* delayed version of this input and the imaginary output is the
48
* filtered output.
49
*
50
* If two floats are connected to the input, then the real
51
* output is the delayed version of the first input, and the
52
* imaginary output is the filtered output.
53
*
54
* The delay in the real path accounts for the group delay
55
* introduced by the filter in the imaginary path. The filter
56
* taps needs to be calculated before initializing this block.
