Interpolating FIR filter with gr_complex input, gr_complex output, and gr_complex taps. 
Interpolating 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[ni] * 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 upsamplers (or interpolators) by specifying an integer value for interpolation
.
