Pulse position modulation is similar to pulse width modulation, but the frequency is not constant. Like pulse width modulator circuit, pulse position modulator can be easily constructed using 555 IC. Here is the schematic diagram of the circuit:
If you look at the output signal plot in the above timing chart, and compare it with our …

A very simple pulse modulator circuit can be built using 555 IC. In 555 chip, a special modulator input is available at pin 5. Here is the schematic diagram of circuit:
This pulse modulator circuit need an external clock signal to work. You can build an astable multivibrator using the same 555 IC or using any …
