摘要： A method for processing an electrical signal comprises receiving an electrical signal comprising a frequency modulated signal encoding digital data; sampling a first portion of the electrical signal to obtain a plurality of samples to obtain a first sample set; determining an index value from the first sample set by assigning a value to each sample in the first sample set based upon an amplitude of the sample; comparing the determined index value with a plurality of predetermined index values to identify a first output value from a plurality of predetermined output values, each of the predetermined index values corresponding to one of the plurality of predetermined output values; and outputting an indication of the output value. Each of the predetermined output values indicates a respective frequency modulation encoded value and the first output value indicates a frequency modulation encoded value within the first portion of the electrical signal.

摘要： A method for processing an electrical signal comprises receiving an electrical signal comprising a frequency modulated signal encoding digital data, sampling a first portion of the electrical signal to provide a first sample set, and determining an intermediate value from the first sample set. A first output value is selected from a plurality of stored output values based on the intermediate value, the output value indicating a frequency modulation encoded value within the first portion of the electrical signal. An indication of the obtained output value is output.
