| Abstract: | In ultrasonic non-destructive detecting system, the electromagnetism noise produced by PWM amplifier badly disturbs the obtaining and analyzing of useful signals. The authors adopt theoretical analyses and simulation experiments to find an effective method of both restraining noise and improving Signal-to-Noise. This method has good effects in practical use. |
