Circuit's FunctionsSawtooth wave can be used as scanning signals and it is a kind of waveform that voltage rises in linear way with the time. This waveform forms mostly by using capacitor constant-current charging and discharging method.This circuit changes output voltage and frequency through altering integration circuit's timing.Waveform slope can be setted by changing integration input current. Circuit's Wrok PrincipleThe integrators A1 starts ponits in VR1 current when the power is switched on.The timer produces timing pulse according to certain time interval.
