Pulse Amplitude Measuring Circuit

The magnitude of pulse A is accurately determined by counting the number of different fractions of that pulse that exceed a given threshold level.

Pulse A is fed into input 10 where it biases transistor 12 conductive. If the full amplitude of pulse A exceeds the given threshold, detector 14 produces a pulse which is recorded by counter 16. Some time later, the pulse attenuated to two- thirds its initial value is applied to the base of transistor 18 through delay circuit 20 and appropriate attenuating resistors 22 and 24. This causes transistor 18 to conduct providing a second input to detector 14.

If this input exceeds the predetermined threshold level the detector produces a second pulse which is also counted by counter 16. like manner, the pulse is further attenuated in a number of steps as indicated, and, after each attenuation, is compared with the threshold level in detector 14. In this way, by counting the number of times detector 14 is triggered into producing a pulse, an accurate measurement of the pulse magnitude can be determined.
