A STUDY ON THE PSEUDOCOLOR ENCODING DISPLAY OF SOUND HOLOSPECTROGRAM

In this paper, a new pseudocolor method to display sound holospectrogram is proposed and studied. On the picture of such a four-dimensional spectrogram, the horizontal axis refers to time, the vertical axis to frequency, the color to phase, and the brightness to magnitude. An example of display is given by employing the realized system.

全息声谱的伪彩色编码显示研究

本文提出了一种全息声谱的伪彩色编码的新方法,并在微机和彩色图象处理器构成的系统上加以实现。所获得的全息声谱以横坐标表示时间,纵坐标表示频率,色彩表示相位谱值,亮度表示幅度值。这样,使得信号的动态功率谱和相位谱得以在二维显示平面上同时表示出,大大增加了频域的信息量。实验分析结果表明,应用本系统所获得的全息谱图具有易于直观判读,特征信息量大,相位分辩率高等优点。
