This document introduces a novel technology for automatic clock calibration. The system receives time signals from a radio station and utilizes them as a reference point to determine the accuracy of the displayed time on the clock. Through a programmatic analysis, the system can adjust the clock to ensure precise timekeeping. The circuit employs active filtering techniques to enhance resistance to interference, resulting in a highly accurate time display. This technology effectively reduces cumulative error in clock synchronization, ultimately improving timekeeping precision.
