信号生成:可以生成各种类型的信号包括正弦波、方波、三角波、扫频信号、调幅波、白噪声、窄带随机信号等-signal generation : can generate all types of signals, including sine, square, triangle wave, sweep signal amplitude wave, white noise, narrowband random signals

谐波信号，可用于数值模拟。是地震信号处理中常用的信号源。-sweep signal and the modeling of seismic

该模型主要实现Chirp系统中Chirp信号的BOK调制，Chirp信号分为上扫频和下扫频信号，可以通过对正余弦信号进行BOK调制来产生。-This model mainly realize the BOK modulation Chirp Chirp signal in the system, under the Chirp signal is divided into the upper frequency sweep and frequency sweep signal, can pass

MATLAB中，chirp扫频产生声音信号，播放同时启动audiorecorder录音，之后对录音做FFT变换并分析其频谱-In MATLAB, chirp sweep signal generating sound, while playing audiorecorder start recording, then do the FFT for recording and analyzing the spectrum
