Implements a PLL which locks to the input frequency and outputs the input signal mixed with that carrier.
input: stream of complex; output: stream of complex
This PLL locks onto a [possibly noisy] reference carrier on the input and outputs that signal, downconverted to DC
All settings max_freq and min_freq are in terms of radians per sample, NOT HERTZ. The loop bandwidth determins the lock range and should be set around pi/200 -- 2pi/100.
