Claim 1
Independent Claim
109 words
THE METHOD OF DETEREMINING THE RESPONSE, TO A TEST SIGNAL PRODUCED BY A GENERATOR THEREOF, OF AN ELECTRICAL NETWORK HAVING INPUT TERMINALS, OUTPUT TERMINALS PROVIDING AN OUTPUT SIGNAL IN RESPONSE TO A SIGNAL APPLIED TO SAID INPUT TERMINALS, AND A CIRCUIT HAVING A STRAY CAPACITANCE NORMALLY SHUNTING SAID INPUT TERMINALS, SAID METHOD COMPRISING THE STEPS OF REMOVING SAID STRAY CAPACITANCE CIRCUIT FROM SAID SHUNTING RELATION, CONNECTING SAID TEST GENERATOR AND AN ELEMENT HAVING A CAPACITANCE EQUAL TO SAID STRAY CAPACITANCE IN SERIES ACROSS SAID INPUT TERMINALS, INTEGRATING THE SIGNAL THEREUPON APPEARING AT SAID OUTPUT TERMINALS TO OBTAIN AN OUTPUT SIGNAL, AND COMPARING SAID OUTPUT SIGNAL WITH SAID TEST SIGNAL.
