Abstract :
A bridge for the comparison of resistance with capacitance in the frequency range 0.2 to 2 kHz has been designed. It is a six-arm generalization of the quad bridge, and makes extensive use of precision amplifiers in both source and detector circuits. It will provide a link between the calculable capacitor and the ac QHR.
