I was reading the c++ code of FM demodulators in gnuradio and I
encountered this in fmdet_cf_impl.cc:109:
-------------------------------------
Sdot = d_scl * (-S0+d_8*S1-d_8*S1+S4);
-------------------------------------
I don't know according to what principle this demodulator work exactly
but it doesn't seem to make too much sense to first add d_8*S1 and then
subtract it.
