Pulse modulation may be subdivided in to two types analog and digital. In analog the indication of sample amplitude is the nearest variable. In digital the information is a code. The pulse position ...

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 ...

The experiment on Pulse Position Modulation (PPM) achieved successful generation and transmission of PPM signals. ... Circuit Diagram: Design: Designing a complete modulation and demodulation system ...
