最近邻插值,在图像处理中，对变换后的图像进行插值(Nearest Neighbour interpolating)

连续相位调制信号(CPM)产生，抑制载波型差分相位调制，可直接计算得到多重分形谱。( Continuous phase modulation signal (CPM) to produce, Suppressed carrier type differential phase modulation, It can be directly calculated multi-fractal spectrum.)

设模拟带通信号频率范围1KHz—1.1KHz，设计一个采样频率8KHz数字频谱分析系统，要求频率分辨率0.1Hz。若对信号直接用FFT进行频谱分析(simulation based communications, with the frequency range 1KHz- 1.1KHz. Design of an 8 KHz sampling frequency digital spectrum analysis system requirements frequency resolution 0.1 Hz. If the signal directly FFT spectrum analysis)
