Tag Archives: Pulse Modulation

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 … Continue reading →

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 … Continue reading →
