Because general electronic parts only have two values of high (1) and low (0), square waves are naturally generated and are widely applied to digital switching circuits. Because the square wave can be rapidly switched from one value to another (i.e., 0 → 1 or 1 → 0), the square wave is used as a clock signal to accurately trigger the synchronization circuit. But if a square wave is represented by the frequency domain, a series of harmonics will occur. This may generate electromagnetic waves and current pulses that affect surrounding circuitry, generate noise and errors, and have significant effects on precision instruments such as analog-to-digital converters (analog-to-digital converters), so the design uses sine waves as clock signals instead of square waves.
