| Abstract: | Based on analyzing the principle of demodulation circuit, a new software demodulation method called half wave demodulation is proposed, and its mathematical principle is given. As an extension of this new method, another new demodulation method called general nulinear transform demodulation is proposed. Application of these two methods for diagnosing fault gear is discussed. |
