| Abstract: | A new design of multiplex digital FM demodulator system was introduced.The demodulator solution by detecting zero and the technology by reducing frequency have been used in the design.So,with keeping the precision of demodulator the project reduces the number of order to digital filter and fits the excursion of the centre frequency iteslf. |
