Below shown circuit diagram is the simplest pulse position modulation circuit using IC-555. With this type of circuit, the position of each pulse changes. Both width and period of the pulses vary with ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits ... demodulation method that’s not so common, but thankfully it’s also pretty easy to understand: the ...
