If you search the archive, you'll find two very mathematical threads on
this under the headers "square wave osc & pwm" and "band limited square
wave". The trouble with many of the mathmatical methods of doing this in
PD is that it is not anti-aliased, so you will get some aliased
frequencies which would not be present in a true square wave.
If you are on Linux, I would recommend using the [plugin~] object with
the BLOP LADSPA plugins. They have a beautiful "analog" sound, can be
pulse-width-modulated, and best of all are bandwidth-limited to get rid
of the nasty little "birdies".
