In the figure is the simple triangular and square wave generating circuit composed of TL082. This circuit consists of the integrator, which is composed of computing amplifier, and the lag comparator circuit. In the figure, R1 and C form a integrating time constant, which is used to change the oscillating frequency. R2 can not only change the amplitude of the triangular wave, but also change its frequency. Besides, the oscillating frequency is effected by the output voltage of the lag comparator. Whether the output LEV is high or not is decided by the op-amp saturation and voltage. Due to the discreteness of the elements, the symmetry of the waveform is effected.
