音調調制
英文
tm tone modulation-

而解碼系統的工作就是將數據串進行解調制和解碼,使之還原為音樂。The calls of non - passerine are some kinds of monotonous dull vocalizations with the characteristics of low and deep frequency, single syllable, low basic frequency and with no ability of modulation in frequency and amplitude. most of the calls are monotonous and low quality mainly based on the basic song. compare the vocal of sub - oscine passerine with non - passerine, they have some similar aspects, but the former possesses of stronger capability of vocal control
非鳴禽的叫聲低沉而單調,音節種類單一,基本音頻率低,缺乏頻率調制以及幅度調制的能力,叫聲的品質因數很低,不悅耳,大多為以基本音為主的單音調低音品叫聲,亞鳴禽的叫聲與非鳴禽近似,但在控聲能力方面又有所提高。The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. in oscine passerine, ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality. as a result, the songs sound well
鳴禽鳴囀的最大特點之一便是其單次鳴唱時間長,鳴唱所包含的音節數量和音節種類繁多,因而由這些音節所組成的句型結構也是復雜多樣富於變化,且由於nxiits嚴格的側別控制(每一側核團只支配同側鳴肌) ,使其具有更強的控聲能力,其鳴聲音調變化幅度大,頻率高,品質因數大,音色好,因而其鳴聲也悅耳動聽。Compared with non - passerine, they appeared longer syllable length, higher basic frequency and more viable frequency ranges. though the amplitude modulation properties enhanced their vocal production, the type of syllable is still stable and less of variety. so the phrase consisted of syllables are comparatively few and changes of the tone are relatively less
且表現出很強的頻率調制特性和特有的幅度調制特性,相對的音節時程比較長,基頻較高且頻率變化范圍較大,所特有的幅度調制特性更增加了其控聲的能力,但其音節的種類仍很單一,缺乏變化,由音節所組成的句型較少,音調變化幅度不大,因此,其叫聲質量盡管較非鳴禽有所改善,但相對鳴禽而言卻又遠遠不如。Characteristics of pulse code modulation for voice - frequencies
