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 ...

Here is a 1Hz pulse/frequency generator using the popular timer IC 555 which is wired as an Astable Multivibrator. The output pulses can be indicated visually by the LED. An Astable Multivibrator, ...

This circuit and its description can be found as figure 13 in the AD8037 data sheet. (from the days when ADI appended lots of lovely app notes). The second pulse generator output (left) can be found ...

The pulse-generation circuit is simply two 555 timer devices, one fed into the other . The first (U5) is set up as a “one shot.” That is, an input trigger causes a single positive pulse to ...
