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.
