Ratio of C2 to C1 determines division ratio, as given in table. When C2 charges to peak point firing voltage of Q2, it fires and discharges C2, so C1 charges to line voltage. Q2 then turns off. Next cycle begins with another positive pulse on base of Q1, discharging C1. Division range can be chanced by utilizing programmable aspect of PUT Q2 and changing ratio of resistances.-R. J. Haver and B. C. Shiner, Theory, Characteristics and Applications of the Programmable Unijunetion Transistor, Motorola, Phoenix, AZ, 1974 AN-S27, p 9.
