Abstract
A decoding method and apparatus capable of automatically adjusting a sampling period is provided. The decoding apparatus decodes a serial code including at least one header pulse and a plurality of data pulses. The decoding apparatus includes a detecting unit for detecting the header pulse to generate an initialization signal, a determining unit for determining a sampling period according to the initialization signal and a pulse width of one of the data pulses, and a decoding unit for decoding the data pulses according to the sampling period.
Claims16
