Publication number: 20230254107Abstract: The present invention discloses a signal communication method having re-sampling mechanism that includes steps outlined below. Sampled data of a data signal is obtained. A time difference between an actual sampling time point and an ideal sampling time point is calculated. A closet time point closest to the ideal sampling time point within a sampling time interval is selected. Operation sampled data within a predetermined range around the target sampled data is selected from the sampled data. A group of response terms are retrieved from a pre-stored lookup table according to the closest time point to substitute the response terms and the time difference into a parameter calculation equation to generate a group of re-sampling response parameters. A calculation is performed based on the operation sampled data and the re-sampling response parameters to generate a re-sampled value of the target sampled data.Type: ApplicationFiled: January 12, 2023Publication date: August 10, 2023Inventors: CHIH-HSIU ZENG, CHANG-MING LEE
