*	gr-analog: Add safety and default for FM preemphasis filter	Andy Walls	2016-03-30	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	The FM preemphasis filter design now precludes the user from inducing a pole on the unit circle at z = -1.0 and z = 1.0. A pole at either of these locations makes the filter unstable and useless: feeding back "+/-inf" into an IIR filter has no good recovery. Also provide a reasonable, maximally safe default of 0.925*fs/2.0 for the high frequency corner, fh. This keeps the slope of the preemphasis filter looking reasonable sane in the whole band; at least for tau=75e-6 and fs=48000.
*	gr-analog: Fix FM preemphasis filter and rework deemphasis filter	Andy Walls	2016-03-29	1	-0/+4
\| \| \| \| \| \| \|	Add working filters designs for the FM preemphasis Tx filter. Rework the FM deemphasis Rx filter as it was easier to rederive the transfer function, than to determine if the one in use was correct.
