I know I've got this technique around here somewhere, but I've just spent two
hours going through the files and another two hours on the 'net and have come up
dry.
Seems to me I remember a pretty nifty way (with xor gates, as I recall) of
making two square waves in quadrature with another. Seems that you took a
binary multiple of the frequency you wanted and gated/flipflopped your way down
to the desired fundamental.
That is, if you want two 1 kHz. square waves in quadrature, you start off with
either a 2 kHz. or 4 kHz. square wave and mogrify those.
Anybody got a clue where I can start looking for this circuit?
