Abstract
A calibrated multi-voltage level system is disclosed having a network of devices, including a first and a second device. The first device comprises a processor for generating data, an encoding unit for encoding the data into a first data signal having multiple voltage levels, and a transmitting unit for transmitting the encoded data signal to the second device. The first device also comprises a calibration unit for sending a first calibration signal to the second device, and for storing a second calibration signal from the second device; and an adaptation unit for correcting the second data signal from the second device with the stored second calibration signal.
