As shown in the figure, the circuit can produce and output square wave, triangle wave and sine wave.It is especially suitable for electronic lovers and students doing experiments with oscilloscopes to observe the signal waveform. This signal generator circuit is simple, low-cost and easy to adjust. 555 timing is connected in a multivibrator form. C2 is a timing capacitance, whose charging loop and discharging loop is R2→R3→RP→C2 and C2→RP→R3→ foot 7 of IC(discharge tube) respectively. Because R3+RP》R2 , the charging time constant and discharging time constant are approximately equal. Output of foot 3 of IC is approximately symmetric square wave.
