DEGARBLER FOR AN INTERROGATOR-TRANSPONDER SYSTEM |
摘要 |
<p>A degarbler for an interrogator-transponder system with a reply code consisting of two framing pulses which enclose code pulses representative of a reply. The degarbler comprises in combination: a shift memory-storing the reply code; framing-pulse detectors connected to the memory, whereby in case an edge of a framing pulse falls within gates generated with the other framing pulse, a framing-pulse detector delivers a signal indioating the presence of a reply code in the memory; a detection triggering unit; and code pulse detectors, whereby the triggering unit ensures that, in the presence of a first reply code or a reply code overlapping a preceding reply code, the appropriate code pulse detector generates a series of gates to pass through the data from the memory to a register forming part of this code pulse detector.</p> |
