In a highly noisy environment, the noise is successfully filtered out to obtain the signal, resulting in an extremely high signal-to-noise ratio. The input signal is +/- 15 mv Sine wave, which passes through a 24-bit A/D converter and then undergoes signal processing to produce a noise-free Sine wave signal.

The following picture is the signal obtained after noise removal processing. The straight line is the position diagram for synchronously controlling the operation of the servo motor.
