This circuit shows the connections required to convert the circuits of Figs. 5-52 and 5-53 to pulse and sawtooth operation. The duty cycle of the output waveforms is given as:and can be varied from 0.1% to 99.9% by proper choice of timing resistors. The frequency of oscillation is given as: and can be modulated or swept by connecting R2 and R3 to common control voltage Vc instead of -Vs.
