Digital Pulse Generator
Intro: Digital Pulse Generator
Digital Pulse generator is used to generate a pulse train. It generates a square wave.
STEP 1: Parts
For making the digital Pulse generator you will need the parts as listed below :-
- IC NE555 with the Stand.
- 10 micro farad capacitor.
- Resistor 2.2k ohm & 10k ohm.
- Variable Resistor of 100k ohm.
You can Buy these Parts from HERE !
STEP 2: Circuit Diagram
Here the Astable configuration of NE555 is used. By varying the Resistance from 0 to 100k you can vary the frequency from 14.4 kHz to 687 Hz and the duty cycle (t/T) varies from 99.99 % to 52.4 %.
The LED is connected at pin no. 3 just for the indication.
STEP 3: Application
Pulse generator can be used for many applications such as:-
- As a clock.
- For testing any device.
- As Modulation Signal.

Unless I'm mistaken, there is a square superimposed over the circuit that, without differentiation, could be mistaken for circuitry wiring. If this is so, it's removal should be contemplated. Other than that, I like these quick and easy circuits.
