ABSTRACT:
An analog store includes a four-arm resistance bridge in which the resistance of one arm is formed by the drain-source path of a field-effect transistor. The bridge is energised across one diagonal by an alternating voltage and the output is derived from the other diagonal through a high-gain amplifier. The input is applied to the gate of the field-effect transistor. A capacitor is connected between the gate of the field-effect transistor and biasing means.
