MATLAB关于FFT频谱分析的程序,可以实现信号的频谱分析(MATLAB on the FFT spectrum analysis procedures, spectral analysis of the signal can be achieved)

很好的超声声场仿真软件，由丹麦理工超声实验室编写。(a good ultrasound simulating software, DTU ultrasound lab. )

利用全通滤波器的原理对于因信号进行改变相位，嵌入数字水印(use of the all-pass filter principle as a result of changes in signal phase, embedded digital watermarking)

离散傅里叶变换对于FDTD计算程序很有用( an algorithm resistant to print/scan process is proposed , which is based on block discrete fourier transform)

无限冲击响应滤波器 (IIR) 实现，涉及一个Butterworth低通滤波器，设计指标为：在通带内频率低于0.2π时，最大衰减小于1dB；在阻带内[0.3π, π]频率区间上，最小衰减要大于15dB (An infinite impulse response filter (IIR) implementation, involves a Butterworth low-pass filter design specifications as follows: in the passband frequencies below 0.2π, the maximum attenuation is less than 1dB in the stopband [0.3π, π] frequency interval , the minimum attenuation greater than 15dB )
