*****************************************************************************************
Note:    the -3dB level is equivalent to 700 mV level in these Bode Plots.

*** Discussion to be added :   


*** The Final Narrow BandPass is BW=100 @ -3dB, and BW=150 @ -12dB.  
*** Slope of bandpass is 5, variation of 5 Hz per dB of attenuation.  
*** Several versions of this design have been tested, and results are similar.

*** Narrow BandWidth of 100 Hz, with 7 Hz spread per dB attentuation.  
*** Notice the Flat-Top PassBand of this Narrow filter.
