Detailed Description

Interpolating FIR filter with gr_complex input, gr_complex output and float 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 float. Taps can be created using the firdes or optfir tools.

These versions of the filter can also act as up-samplers (or interpolators) by specifying an integer value for interpolation.
