Frequency and duty ratio can be varied independently to generate desired rectangular wave. Uit is used in conventional sawtooth generator. Two transistors provide positive going output when uit emitter voltage exceeds npn emitter voltage. Frequency range is 60 to 1,000 cps.- Transistor Manual, Seventh Edition, General Electric Co. 1964, p 344.
