Abstract
The first and second time-domain signals are received, and a difference between the pulse width of the first time-domain signal and the pulse width of the second time-domain signal within a unit time for carrying one item of analog signal information is obtained. The obtained difference is treated as positive information if the pulse width of the first time-domain signal is greater than the pulse width of the second time-domain signal, or as negative information if the pulse width of the first time-domain signal is smaller than the pulse width of the second time-domain signal.
