International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In order to reduce the measuring channels for the single-transient signals, the author propose the time division multiplex technique and introduce the method of SAW delay line in this paper. That used method of SAW tap-delay line in this system is different from previous methods consists in making traditional method, which is one-path signal input different delayed multi- path signals output, alter new method, which is simultaneous multi-path signal inputs that are respectively delayed and one-path signal serial output.
