gnuradio.analog.probe_avg_mag_sqrd_c(double threshold_db, double alpha = 0.0001) → sptr

compute avg magnitude squared.

Input stream 0: complex

Compute a running average of the magnitude squared of the the input. The level and indication as to whether the level exceeds threshold can be retrieved with the level and unmuted accessors.

Constructor Specific Documentation:

Make a complex sink that computes avg magnitude squared.

Parameters:

• threshold_db – Threshold for muting.
• alpha – Gain parameter for the running average filter.
