The trapezoidal wave generator showed as the picture(b) can be output when the picture (a) circuit is used.The trapezoidal wave's time t1 ~ t2 can be adjusted independently.Time T1 regulates via regulating capacitor C1 crudely,potentiometer fine respectivly.t2 is adjusted via regulating capacitor C2 crudely ,RP2 fine respectivly.t1+t2 fix the cycle or frequency.t3's change depends on potentiometer RP3 and its value is calculated as t3=CRE·UA/UE.Here RE is total PNP transistor shot extremel resistance, UE is emitter drop,UA is output voltage amplitude.
