Abstract :
A `1kT-pulse¿ excitation of a high-Q-factor LC ringing circuit is defined, and a filter configuration is described which allows the detection of such a pulse with good s.n.r. (signal/noise ratio) and excellent ¿r, (resolving time). S.N.R.s considerably larger than unity were found experimentally, in reasonable agreement with theoretical calculations.
