半導體參數分析儀,各種信號發生器,示波器,邏輯分析儀,萬用表,絕緣電阻測定器,絕緣耐壓檢驗器,噪音檢驗器,恆溫槽。The statistic of wavelet transform coefficient algorithm can solve the periodic noise, high - energy noise and some non - gauss noise simply and effectively ; bi - spectrum can acquire more information from the original signal than power - spectrum, detect more information except from range and restrain the gauss noise. short - time speech signal can be considered as stationary and with periodic non - gauss signal, so we can make use of bi - spectrum to obtain the speech character and separate the speech and noise and detect morse telegraph signal ; complex number spectrum variance algorithm is put forward based on the deeply observing speech data, it is a new algorithm, experiment show that it is simple, effective
統計演算法在解決周期信號、高能噪聲和高斯信號方面有獨特之處,能簡單有效提取以上噪聲的特徵;雙譜能夠提供比功率譜更多的有用信息,有效地檢測信號幅度之外的其它信息,並能有效抑制高斯噪聲,短時語音信號一般認為是平穩且有一定的周期性的非高斯信號,因而可以利用雙譜來提取語音信號特性並實現信噪分離;復數譜方差演算法是在對語音信號進行深入觀察和分析的基礎上而提出來的一種全新的語音特徵提取方法,此方法簡單而有效的提取了語音、噪聲的特徵以及檢測莫爾斯信號,基於實驗表明,該演算法取得了很好的效果。The main research content of the article is involved as follows : ( 1 ) the research and discussion of the quantitative metallographic analysis methods and the measuring methods of micro hardness.
