  • Abstract
    In the time-division multiplier the product x1·x2 is formed by pulse-duration modulation with x1 and amplitude modulation with X2. The circuit can be arranged in such a manner that division by means of a quantity x3 can be carried out simultaneously, the output being x1·x2/x3. When transistor switches are employed the error is 1·10¿4 machine units only. The zero error for X2, used for amplitude modulation, can be reduced to 2·10¿5 machine units.
