  1. In order to study the effect of weak noise on the sound signal extraction of mouse ( mus musculus km ) inferior collicular ( ic ) neurons from environment, we examined the change in frequency tuning of neuron induced by a weak noise relative to 5 db below minimum threshold ( remt - 5 db ) of tone. 12 healthy adult mice ( 20 - 25 g, b. wt. )

    本實驗旨在探討弱噪聲對小鼠( musmusculuskm )中腦丘( inferiorcolliculusic )神經元聲信號提取的影響及其神經機制,我們選用相當于純5db的白噪聲( whitenoise ) ,比較加入噪聲前後神經元頻率調諧曲線的變化和注射-氨基丁酸( - aminobutyricacid , gaba )能受體拮抗劑荷包牡丹堿( bicuculline , bic )后對該變化的影響。
  2. The matching pursuit techniques are applied to enhance speech signal, and a method to determine the threshold of coherent ratio is provided in the enhancement procedure based on matching pursuit. with the method, the noisy signal can be efficiently enhanced in a rather wide range while the statistical property of signal and noise is unknown

    運用匹配跟蹤技術處理了語信號增強問題,給出了匹配跟蹤信號增強過程中相干比值的確定方法,實現了在未知信號與噪聲統計特性的情況,在相當大的范圍內明顯增強信號的目的。
