Abstract
A system and method for decoding quadrature signals includes a quadrature signal generator, a quadrature signal decoder, a key matrix and a driver. The quadrature signal generator generates quadrature signals on rotation. The quadrature signal decoder is configured to convert the quadrature signals into non-overlapping signals. The key matrix is configured to receive the non-overlapping signals. The driver is configured to scan the key matrix to decode the non-overlapping signals to generate an event update corresponding to a direction of rotation of the quadrature signal generator.
