UWB technology is a new exploration of the use of radio spectrum resource and it inaugurate a new field of time domain application of electromagnetic wave.───利用UWB技术是对无线频谱资源的利用进行的新的探索,开辟时域电磁波应用的新领域。
Spectrum of the amplitude-modulated wave is observed by a radio frequency spectrum analyzer and amplitude values of every spectrum are recorded at the upper sideband or lower sideband.───用射频频谱分析仪观测一个已调波的频谱成分,记录上边带或下边带中各条谱线的幅度值,从而可以根据有关算式计算出调制信号(音频信号)的失真度。
