Differential Transformer Bridge Operated by Square Waves
W. A. PROWSE & ELIZABETH LAVERICK
Top of pageAbstract
THE use of inductively coupled ratio arms in a bridge energized by square waves has been studied in these Laboratories, with particular reference to the analysis of condenser-resistance combinations. It has been found, in general agreement with Yates's statement1, that the output forms shown by a cathode ray oscillograph, as balance is approached, afford a means of discriminating between parallel and series combinations of capacitance and resistance.
