Re: Pease tuneable MFB band-pass filter
|
Being lazy, I searched for "another single pot tunable band pass network called Hall¡¯s network"
Thank you:Do you have a reference to it?
Google doesn't help, because the name has been re-used. The
Pease circuit will tune over a decade with 100:1 change in R2
value, which is just about practicable, 100 ohms/100k.

it can tune over a decade. The commercial worked example is
used in the general radio model 1232a tuned amplifier/null
detector. It is a different circuit than Pease¡¯s.
