ABSTRACT:
Digital ratiometer and amplitude analyzer using such a ratiometer.
It is possible to solve the problems of the calculation and display of the ratio of two or more quantities, provided that the latter are converted into frequencies. Counting registers are used for evaluating these quantities. The filling of these counting registers (6,13) is prevented by bringing about a shift to the right (10,19) of all the registers as soon as (15) one of them is filled.
