Pease tuneable MFB band-pass filter
¿ªÔÆÌåÓýI have uploaded the above as a .ZIP. According
to Bob Pease, the gain at the peak should be close to 34 dB,
independent of the tuned frequency. I don't get either of those
results using version 24.1.8. However, the bandwidth is fairly
constant with frequency, as predicted. I can't believe Bob Pease
reported the performance in error. --
