Varying the amount of this comparator circuit's hysteresis makes it possible to vary output frequencies in the 740-Hz to 2.7-kHz range smoothly. The amount of hysteresis to-gether with time constant R6C1 determines how much time it takes for C1 to charge or discharge to the new threshold after the output voltage switches.
