Detailed Description

FIR filter with gr_complex input, gr_complex output, and gr_complex taps.

The fir_filter_XXX blocks create finite impulse response (FIR) filters that perform the convolution in the time domain:

   out = 0
   for i in ntaps:
      out += input[n-i] * taps[i]

The taps are a C++ vector (or Python list) of values of the type specified by the third letter in the block's suffix. For this block, the value is of type gr_complex. Taps can be created using the firdes or optfir tools.

These versions of the filter can also act as down-samplers (or decimators) by specifying an integer value for decimation.
