[sdiy] (easy) resonant filter

[patchell]

    Go to the Paia website.  Locate the article from Radio Electronics on
building the 2700 synth.  There is a bandpass filter that uses 1 transistor and
two diodes as the only active elements.  It had a rather "unique" sound.  But, I
would have to say that this was the simplest resonant filter I ever saw.
