In the figure is the multi-waveform generating circuit of good functions. This circuit is fixed with 4 high impedance computing amplifiers, which can generates low-frequency, ultra-low-frequency, triangular and sine wave. In the figure, A1 functions as the voltage rectifier, A2 forms the integrator, the integration capacitor is selected by the switch. A1 and A2 are connected in a loop, which compose a typical triangular and square oscillator. The output stable pipe of A1 is used to stabilize the amplitude of the square wave, and it also increases the stability of the whole circuit.
