This is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator with a 50% pulse duty cycle. The difference from the standard design of a 555 ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you ... Triggering ...

I have wanted to make a pulse generator for years ... The input resistor network in the circuit is there to turn the unipolar input signal into a bipolar signal within the IC’s ±3.5V clamping range.
