I need to convert a phasor into a square wave in this way:
phasor:
/ / / / / / / | / | / | / | / | / |/ | / | / | / | / | / | / |/ |/ |/ |/ |/ |
square (2:1): ________ _________ _ | | | | | | | | | | | |____| |____|
so, a relation HIGH:LOW holds a high or a low value (1 or 0) a indicate number of cycles.
Check out doc/3.audio.examples/J02.trapezoids.pd for a patch that can make all kinds of waveforms with jumps (discontinuities) from a phasor signal. In that patch, if the Amplitudes add up to 0 you get a waveform with only horizontal segments.
For your 2:1 square wave, just set the amplitudes of the first two wrap-phases to 100 and -100, and the phases to e.g. 33 and 66.
For the theory behind this technique read the final chapter in Miller's book, e.g. http://crca.ucsd.edu/~msp/techniques/latest/book-html/node186.html
