| Abstract: | A pulse width modulation and demodulation method based on natural samples is discussed. Spectral properties of PWM pulse.trains is analysed and a plan of direct mutiplexing transmission for RF television signals in CATV systems is introduced. presenting advantages of the plan and comparing several analog modulation with pluse width modulation, the article considers that PWM modulation technology be very attractive and potentially applicable in analog signals multiplesing transmission. Therefore,it will be widely used in intergrate service network of the future. |
