Method and system for processing information
A method and apparatus for processing information includes receiving electronic information at a second device from a first device, where the received electronic information is sampled periodically, resulting in a plurality of numerical data value samples. The data value samples are analyzed within the receiver to determine slope transitions within the data which are interpreted as high and low transitions representative of bit transitions ordinarily seen in the transmission of digital data. The bit transitions are then converted into a receiving device appropriate usable and readable form, such as bytes (8 bits each) or groups of bytes, as needed. Data bytes may be commands, information, or other indicators useful to the receiving device.
