ABSTRACT:
A polar display representing the ratio of two input signals is provided by exponentiating the logarithmic ratio of two input signals. The DC voltage thus produced, which is proportional to the ratio between the two input signals is then multiplied by a constant amplitude AC signal derived from one of the input signals and thus converted to an AC signal which is phase coherent with that input signal. This AC signal is then split into its orthogonal components, using an AC signal derived from the other input signal, to generate the X and Y coordinate of the polar diagram.
