ABSTRACT:
The peaks of synchro or step data representative of compass heading are detected and the resulting logic levels are latched into a register by an enable pulse generated in response to the data itself. Three outputs from the register are fed directly to the computer input port and provide 1/6.degree. resolution and 1.degree. range. Two of the register outputs are decoded and used to operate an up/down counter. The output of the counter is applied to the computer input port and provide 1.degree. resolution and 16.degree. range.
