I have a shaft position encoder that generates Sin and Cos signals, i need to display the shaft angular position in degrees using an analog meter.
I need an analog circuit that will compute the arctangent of the quotient of the Sin and Cos magnitudes.
Angular position = arctan sin/cos.
The Sin and Cos magnitudes have a +5V to -5V excursion.
Piece of cake, isn't it?
Any help on this subject will be greatly apppreciated.
