CONVERTION OF SAWTOOTH WAVE GENERATOR IN TO TRIANGULAR WAVE GENERATOR

Here am going to explain convertion of sawtooth waveform generator using op-amp in to triangular wave generator.
The difference between the triangular wave and sawtooth waveform is that the rise time of triangular wave is always equal to its fall of time while in saw tooth generator, rise time may be much higher than its fall of time , vise versa .




It can be done by use of a potentiometer (47K) . Use of the potentiometer is when the wiper is at the centre , the output will be triangular wave since the duty cycle is 50%.


And after the working is same as is explained in the triangular wave generator using op-amp.


Components for wiring this circuit

Op-amp ic A1=A2 - 741C
R1 - 1K
R2 - 180 Ω
R3 - 12K
R - 47K
C - 0.1μF
