Abstract
Practical measurements on a digital PPM system handling 8Mbit/s PCM data show good correlation with theoretical results obtained from a computer model of the system. It is confirmed that there exists an optimum number of time slots which maximises the receiver sensitivity, and that a digital PPM system can offer an improvement of 4-2 dB over an equivalent binary PCM system when the fibre bandwidth is several times that required by PCM.
