The Reticon (last I heard acquired by EG&G) FIR filters (part no. RT5602, if memory serves thi; /archives//html/Amps/2001-01/msg00419.html (9,310 bytes)

The bucket brigade approach does indeed make an FIR filter possible without resorting to a DSP. 73, Doug, K4DSP -- FAQ on WWW: http://www.contesting.com/F; /archives//html/Amps/2001-01/msg00423.html (8,832 bytes)

Common filters implemented with op amps or LC networks are continuous time filter; /archives//html/Amps/2001-01/msg00439.html (11,002 bytes)

Make the bandwidth narrow, and the rise and fall times always increase. It is this "softening" that most people call ringing, because it "blurs"; /archives//html/Amps/2001-01/msg00450.html (9,737 bytes)
