Claim 1
Independent Claim
129 words
A CIRCUIT FOR MEASURING THE DIFFERENCE BETWEEN THE INTEGRATED AMPLITUDE OF TWO SETS OF PULSES, SAID CIRCUIT COMPRISING FIRST AND SECOND INTEGRATING CIRCUITS, MEANS TO APPLY PULSES OF ONE SET TO SAID FIRST INTEGRATING CIRCUIT, MEANS TO APPLY PULSES OF THE OTHER SET TO SAID SECOND INTEGRATING CIRCUIT, A DIFFERENTIAL AMPLIFIER HAVING FIRST AND SECOND INPUTS AND AN OUTPUT, MEANS TO CONNECT THE FIRST AND SECOND INTEGRATING CIRCUITS RESPECTIVELY TO THE FIRST AND SECOND INPUTS OF SAID DIFFERENTIAL AMPLIFIER, MEANS TO VARY THE TIME CONSTANT OF SAID SECOND INTEGRATING CIRCUIT, A METER, MEANS INCLUDING SAID METER AND CONNECTING THE OUTPUT OF SAID AMPLIFIER TO THE SECOND INPUT THEREOF, A SOURCE OF UNIDIRECTIONAL SIGNAL, AND AN IMPEDANCE TO APPLY SAID UNIDIRECTIONAL SIGNAL TO THE SECOND INPUT OF SAID DIFFERENTIAL AMPLIFIER.
