使用MATLAB 中的 wgn() 函式生成白噪聲 如果要向訊號中新增白噪聲,可以使用 wgn() 函式,該函式生成以伏特為單位的高斯白噪聲樣本。該函式的第一個和第二個引數是白噪聲的 m×n 矩陣,第三個引數是噪聲的功率,第三個引數是負載的阻抗,以歐姆為單位,依此類推。例如,讓我們生成一個 101×1 的高斯白噪聲...
Consider the linear system defined by Generate 1500 samples of a unit-variance, zero-mean, white-noise sequence xn, n = 0, 1, . . . , 1499 and filter them through the filter H to obtain the output sequence yn. Compute the sample cross-correlation ˆRyx(k) for k ...
Open in MATLAB Online Hello everyone. I am trying to generate two independent and uniformly distributed white noise e(t) and u(t) wich have "mean = 0" and "variance = 1". Since they are independent, their cross-correlation must be "0" for all time lags theoretically. So i have ...
I want to generate correlated complex white Gaussian noise signals in MATLAB. What I do is that I take complex Gaussian random variables with unit-variance and multiply them with the desired input covariance matrix. Next I have to send this signal through a bandpass filter to get the desired ...

Second: To use the in-built function to add noise to the colored image directly. eg. imnoise() in Matlab. I tried with both the methods (imnoise and independently), I got the same result. Share Improve this answer Follow answered Jul 9, 2019 at 5:12 Deepak 9911 silver badge44 bronze...
and how to simulate sine wave and sin wave+ noise in modelsim altera --- Quote End --- shift register based prbs can generate pseudo random noise. LUTs also can be used to store whatever type of noise you get from tools like matlab e.g. gaussian. You add noise signal to your...
