we have a photo camera with DC Motor and closed loop controller is equal k/s^2+s+k. first,we shoul find ZOH,then we identify the system with ARX model that na=nb=2 Here,we want to identify the Dynamic Linear System. we use different inputs such as normal distribution,uniform distribution,...

16QAM编译码程序，在信号调制过程中是不可缺少的成分(16QAM encoding and decoding process, in the course of signal modulation is an indispensable ingredient)

利用自适应RLS算法消除信号中的工频干扰，纯净信号选为数字调幅信号8ASK，工频干扰为一余弦信号，滤波后取得的很好的效果。(Adaptive RLS algorithm for the elimination of the use of signal-frequency interference, and pure signal selected as the digital AM signal 8ASK, power-line interference is a cosine signal, after filtering achieved very good results.)

A fast customizable function for locating and measuring the peaks in noisy time-series signals. Adjustable parameters allow discrimination of "real" signal peaks from noise and background. (A fast customizable function for locating and measuring the peaks in noisy time-series si gnals. Adjustable parameters allow discrimin ation of the "real" signal peaks from noise and back ground.)
