Abstract
Disclosed are a spread-spectrum decoding method for a transmitted signal and a display apparatus. The method comprises: acquiring a fixed input frequency of an input signal, and taking the fixed input frequency as a decoding frequency; performing a calculation according to the fixed input frequency to obtain a cycle number N of the input signal within a pre-set time range; determining whether, during the pre-set time range, the ratio of the number of cycles corresponding to the input frequency after the spread-spectrum processing, which is greater than or less than the decoding frequency, to the cycle number N is greater than or equal to a pre-set percentage; if so, adding a one stage pre-set adjustment frequency value to the decoding frequency or subtracting same from the decoding frequency so as to obtain a new decoding frequency; and taking the new decoding frequency as an updated decoding frequency.
