   AF'V'    
                                    Variable Two-Filter  version of the  'AFX' project
 

The below circuit and plots are NOT spectacular but were given a fair test.
... Goal was to test use of only Two MFB filters .  

... Dual Notches could not be well developed when using only Two MFB filters. 
...    More phase alignment is required to generate the Dual Notches. 
...    Therefore, No Notches are presented in the below plots. 
... Adjustable in real-time from 600Hz continuous to 800Hz 
       by a single front-panel mounted 5K Pot for User Real-Time Control.   

*******  AFV_3RL-2VF-VQ *******     Easy to set-up, wider BandWidth, not compatible with Dual-Notch-Method. 

******* 3 Roof-Filters  /  Active-Limiter  /  2 Variable-Same-Filters  /  Variable-Q20-Filter    *******

*** AFV_3RL-v2F-vQ-v1-S  design : 
***  (1) with Three Roof Filters 
***  (2) with only Two MFB filter stages 
***  (3) with R(freq) controlled by a Two-Gang Pot 
***

******* Example of Variable f(0) using a single panel mounted Pot.    



*** Example of "not so spectacular" Band-Pass from this design from Magnitude Plot.  

************************ Example of Variable f(0) for lowest, middle , and highest adjustment.
