Patent 8699371 was granted and assigned to Infineon Technologies on April, 2014 by the United States Patent and Trademark Office.
A method of receiving a data transmission includes detecting a first switching of a transmission signal to a first signal value, starting a duration measurement of a first time interval that begins with detecting the first switching of the transmission signal, detecting a second switching of the transmission signal to a second signal value, stopping the measurement of the first time interval duration and starting a second duration measurement of a second time interval, detecting a third switching of the transmission signal to the first signal value or to a third signal value, stopping the second measurement in response to detecting the third switching, determining a relation of the first and second time interval durations from the first and second measurements, and determining a data value of the transmission signal based on the determined relation.
