The circuit shown in Figure 5-7 is a multi-vibrator circuit composed of 555 and constant current charging and discharging circuit and C1. IC2 uses 5G28C as a high input impedance follower to play the role of isolation and impedance transformation. Oscillators are constant current charging and discharging, so the sawtooth has a good linearity. RP1, RP2 are used to adjust the charging and discharging time constant and the duty cycle. Icon parameter cycle is 0.2ms ~ 60s. When K1 is closed, it produces sawtooth, of which period is half the triangle wave.
