Bandwidth (signal processing) or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz Bandwidth (computing) or digital bandwidth: a rate of data transfer, bit rate or throughput, measured in bits per second (bps) Spectral linewidth: the width of an atomic or molecular spectral line, measured in hertz

说明：  噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)
