With the interference-to-noise ratio reduced to 30 dB, plot the adaptive antenna pattern after 200 iterations of the LMS algorithm-With the interference-to-noise ratio of red uced to 30 dB. plot the adaptive antenna pattern after 200 ite rations of t

test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。-test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as t

本程序用在测试采煤机煤矸识别系统中，验证小波算法-Wavelet Algorithm for caving coal

光学领域，常用单位换算包括：dbm和w的换算，db 和输入输出的换算-power conversion include the translating between W and dBm

This function displays the PSNR (peak signal-to-noise ratio) between two images. The answer is in decibels (dB). PSNR is very common in image processing. A sample use is in the comparison between an original image and a coded/decoded image. Typica
