This might be a silly question. But here goes ...
In gr_fractional_interpolator_ff I observed that to make the filter interpolate between input values you have to set the interpolation ratio < 1 and this is because the block has this line in the code "set_relative_rate (1.0 / interp_ratio)". I always thought for a block named interpolator a value of interpolation_ratio > 1 would be understood as increasing the sampling rate by that factor. Is this not correct?
