A system for decoding frequency modulated signals includes a glue logic module, a key matrix, and a driver coupled to the key matrix. The glue logic module provides a pre-scaled frequency signal, while the key matrix receives the pre-scaled frequency signal. The driver decodes the pre-scaled frequency signal to generate at least one event update corresponding to a frequency of the pre-scaled frequency signal.

Frequency modulated signal decoding using a driver

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.
