37
* The block takes one or two float stream and outputs a complex
38
* stream.
39
*
40
* If only one float stream is input, the real output is a delayed
41
* version of this input and the imaginary output is the filtered
42
* output.
43
*
44
* If two floats are connected to the input, then the real output
45
* is the delayed version of the first input, and the imaginary
46
* output is the filtered output.
47
*
48
* The delay in the real path accounts for the group delay
49
* introduced by the filter in the imaginary path. The filter taps
50
* needs to be calculated before initializing this block.
