[Discuss-gnuradio] how long is the averaging length of the SNR estimator?

2011-04-05 Thread William Cox
Looking at the documentation for "gr_probe_mpsk_snr_c" ( http://gnuradio.org/doc/doxygen/classgr__probe__mpsk__snr__c.html), it says it computes a running average of the signal mean/variance. How long is this running average? Meaning, if my SNR is changing over time, how much will past values affec
