Abstract:
A method for determining a bit sequence from by an analog waveform representing the bit sequence and at least one other parameter associated with the analog waveform, the method comprising:periodically converting a current amplitude of the analog waveform into a current number; converting at least one other parameter associated with the analog waveform into at least one other number; synchronizing in time the current number and the at least one other number in response to each conversion of the analog waveform to the current number; concatenating the current number and the at least one other number to form an address in response to the current number and the at least one other number being synchronized; addressing a memory with the address in response to concatenating the current number and the at least one other number, the memory storing a respective bit predetermined for each address; and outputting each respective bit addressed from the memory to form the bit sequence.
