运用FFT技术来综合和分析电话拨号的过程,matlab来分解了这一过程,希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing
The dual tone multi-frequency (DTMF) standard specifies that the tone
generated by a button on a telephone key pad is the sum of two sinusoids,
with frequencies determined by the button s row and column.
The dial pad on the upper left allows you to select buttons and generate
the corresponding tones.
The signal plotted on the upper right is a recording of the FAX number
for the MathWorks being dialed. You can replay the entire signal, or
select individual segments. The power plot is the magnitude of the FFT
of the signal being played. What is the MathWorks FAX number?)

车辆监测用测速雷达是依据多普勒效应原理实现的。由雷达发出一束微波,遇被测目标(车辆)时微波被反射回来,再由雷达接收反射波。如果目标相对于雷达有距离上的运动,反射波的频率将与发射频率发生差异,而这种差异的大小正比于目标与雷达的相对运动速度。于是,雷达通过检测反射波频率和发射波频率的差,就可以计算出被测车辆的移动速度。本次课程设计是利用离散付里叶变换进行频谱分析,设计数字滤波器组,并对滤波器组加窗降低副瓣,通过频域方法测量速度。(Vehicle monitoring using radar gun is based on the realization of the principle of the Doppler effect. By the radar emits a microwave, in case the measured target (vehicle) when the microwave is reflected back, and then by receiving the reflected radar waves. If the target relative to the radar on a distance of motion, the frequency of the reflected wave and the emission frequency of the difference, and this difference is proportional to the relative target and radar velocity. Thus, by detecting the reflected radar wave frequency and the frequency difference between the transmitted wave, we can calculate the movement speed of the vehicle under test. This course is designed to take advantage of the discrete Fourier transform spectral analysis, digital filter design group, and filter bank windowed lower sidelobes by frequency domain methods to measure speed.)
