Pulse Code Modulation Systems DesignThis text explains basic PCM concepts and performance parameters, and provides key methods for estimating system performance and transmission loss. More advanced, practical sessions cover PCM symbols, modulation and demodulation techniques, and detection and synchronisation problems. There are also design charts containing various PCM signalling methods that can be used to calculate system performance as you go along, and ready-made performance parameter formulas and system equations which readers will be able to import directly into their calculators or PCs. |
