frequency modulation distortion

基本解释

The fundamentals of LFM(linear frequency modulation) signals, waveform parameter design, system control, quality analysis and pre-distortion calibration are discussed in this paper.
本文讨论了线性调频信号的基本理论，研究了信号参数设计、系统控制、性能分析与预失真校正。
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.
补偿、校正系统幅度或相位频率特性，以减小畸变或达预定目的的网络。分幅度均衡器和相位均衡器两种。可提高电路的传输质量。常用于电话、电报、电视、音响等设备中。
