A pulse detection system comprises, in series, a pulse amplitude detector, a pulse width detector and a recorder. The pulse amplitude detector comprises a voltage comparator having an input for receiving a voltage pulse, a reference d.c. voltage input, a ground and an output for producing an output voltage when the input pulse equals a predetermined fraction of the reference voltage. The pulse width detector comprises a positively-triggered monostable having a trigger input connected to the comparator output, a ground, a RESET, a RESET reference, a reference d.c. voltage input connected through a resistor to the RESET and through a capacitor to the RESET reference, and a Q output and a positive-going clocked flip-flop having a clock input connected to the Q output of the monostable, a data input connected to the comparator output, a ground, a reference d.c. voltage input, a RESET, and a Q output connected through a delay resistor to the RESET and through a capacitor to ground. The recorder is a conventional digital counter. Author
