Below : Magnitude plot showing measured dept of the Dual-Notches. 
Green trace is the Differential-Dual-Notch .       Red trace is the Q20 Sharp Filter.

***********************************   Notice that the  600 - 700 - 800 waveforms  have good BandPass shapes. 
*** the very wide signal is the Roofing Filter Output, which will restrict the variability of the central f() signal

****************
Notice that at all three frequencies, the peak amplitude of the final signals stay within 0.3 dB of the f(700) signal.
