Abstract

Pulse width modulation (PWM), a member of pulse time modulation (PTM) techniques, has been found advantageous for transmission of digital signals over optical fiber links. Most of the data is often found in Pulse Code Modulated (PCM) form and therefore needs to be converted into Pulse width modulation. A simple and low-cost circuit for the conversion of pulse code modulation (PCM) to Pulse Width Modulation (PWM) is proposed. The circuit has been tested in hardware and the experimental results are quite satisfactory. The circuit for the conversion of PWM to corresponding PCM is also proposed.
