Patent ID: 7376189

Claim:
A remote control signal reception circuit, comprising: first sampling means for sampling an input data signal to carry out quantization of said input data signal using a first sampling frequency that is higher than a frequency of said input data signal, and storing a result of the quantization in storing means; and correcting means for carrying out correction of said result of the quantization stored in said storing means according to each result, and outputting a result of the correction as quantization data, wherein: when said result of the quantization is low-level, the correcting means outputs a low-level as the quantization data, and when said result of the quantization is high-level, the correcting means detects a change from high-level to low-level, and modifies results of the quantization from high-level to low-level for a predetermined number of sampling periods of the first sampling means, which number is counted backward from the change from high-level to low-level, and then outputs a result of modification as the quantization data.
