gr_make_probe_avg_mag_sqrd_f (double threshold_db, double alpha)

Detailed Description

compute avg magnitude squared.

input: float

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.
