filter
- ％ y=filter(sig,fmin,fmax) ％ 对信号进行理想滤波，可完成低通，带通 ％ sig为被滤波信号 ％ fmin为下限频率，当fmin为0时为低通滤波器，当fmin>0时，为带通滤波器 ％ fmax为上限频率，fmax>fmin ％ fs为信号的采样频率 ％ y为经过滤波后的信号 -％ Y = filter (sig, fmin, fmax)％ of the ideal signal filtering, to be com
a
- NAME: bpass PURPOSE: Implements a real-space bandpass filter which suppress pixel noise and long-wavelength image variations while retaining information of a characteristic size. CATEGORY: Image Processing CALLING SEQUENCE
b
- cntrd: calculates the centroid of bright spots to sub-pixel accuracy. Inspired by Grier & Crocker s feature for IDL, but greatly simplified and optimized for matlab INPUTS: im: image to process, particle should be bright spots on dark
FIR

times_four_carrier_recovery
- 实现了OFDM信号的四倍载波恢复，通过带通，滤出4fc。-Four times to achieve the OFDM signal carrier recovery, through a bandpass filtered off 4fc.
besselfilter
- % besselfilter. Function to implement a bandpass Bessel Filter. % Inputs: % order: Number of poles in the filter. Scalar numeric value. % low: Lower frequency bound (Hz). Scalar numeric value. % high: Uppe
程序
- 通过对随机信号的处理，将其转换为带限信号，再将其通过不同阶数的带通滤波器，得到滤波后的信号。(By processing the random signal, it can be transformed to band limited signal, and then pass the bandpass filter with different orders to get the filtered signal.)
