Filter Design in Multiplex Receiver
Feng Wen · Journal of Chongqing University of Posts and Telecommunications · 2001
In production of logging of oil field, multiplex signals are transmitted by single cord. The receiver shunts demodulation by useing bandpass filter, and interference depends on performance of bandpass filter. This paper use cascade between bandpass filter and band elimination filter to improves filtering performance, and also presents analysis results and design formula. The practical aplication shows satisfactory results.
