A waveform is a shape that represents changes in amplitude with respect to time. A periodic waveform includes sine wave, square wave, triangular wave, sawtooth wave. On the x-axis, it indicates the time and on y-axis it indicates amplitude. Many people frequently get confused between triangular wave and a sawtooth wave. The sawtooth wave generator is a one kind of linear, non sinusoidal waveform, and the shape of this waveform is a triangular shape in which the fall time and rise time are different. The sawtooth waveform can also be named an asymmetric triangular wave.
In this work, a sawtooth wave generator was constructed using transistor and a simple 555 timer IC. The circuit consists of a transistor, a capacitor, a Zener diode, resistors from a constant current source that are used to charge the capacitor. Initially, let us assume that the capacitor is fully discharged. The voltage across the capacitor is zero and the 555’s output is high because of the internal comparators connected to the pin 2 as shown in the chapter three of this work.
