schematic to change square wave to triangular wave

This schematic to awaken triangular wave entirelyly 512 step of cycle. IC1 and IC2 is two chopper four bits fluctuates connected as chopper 8 bit, added with doorstep network Resistor, what interfaced to binary output to triangular wave.

If square wave is given to bell input, rising count network will finite of chopper reachs 255, where output of carry would be low and turns on latch on IC3. Then count downwards so reaching null, and then output of carry returns to turn on latch on IC3, that way further. Applies tolerance resistor 1% to guarantee every same step.
