frequency modulation distortion

基本解釋

The fundamentals of LFM(linear frequency modulation) signals, waveform parameter design, system control, quality analysis and pre-distortion calibration are discussed in this paper.
本文討論了線性調(diào)頻信號(hào)的基本理論，研究了信號(hào)參數(shù)設(shè)計(jì)、系統(tǒng)控制、性能分析與預(yù)失真校正。
In the multi-carrier modulation of DMT communication system, both time domain and frequency domain equalizers are used to compensate for the magnitude and phase distortion within each subchannel.
補(bǔ)償、校正系統(tǒng)幅度或相位頻率特性，以減小畸變或達(dá)預(yù)定目的的網(wǎng)絡(luò)。分幅度均衡器和相位均衡器兩種。可提高電路的傳輸質(zhì)量。常用于電話、電報(bào)、電視、音響等設(shè)備中。
