1D Gaussian filter to remove noise (with code)

Code: clc clear all close all warning off x=cumsum(randn(1,10000)); plot(x); title('Original Noisy Signal'); g=fspecial('gaussian',[1 100],10); figure; plot(g); title('Gaussian Low pass Filter'); y=conv(x,g); figure; plot(x,'b'); hold on; plot(y,'r','linewidth',2); legend('Noisy Signal','Signal after noise removal'); You can refer this video to understand the effect of changing standard deviation of Gaussian Filter in removing noise-- https://youtu.be/VBS8zKT4z94 Learn Digital Signal Processing using MATLAB: https://www.youtube.com/playlist?list=PLjfRmoYoxpNr3w6baU91ZM6QL0obULPig Learn Complete Image Processing & Computer Vision using MATLAB: https://www.youtube.com/playlist?list=PLjfRmoYoxpNostbIaNSpzJr06mDb6qAJ0 Learn Complete Machine Learning & Data Science using MATLAB: https://www.youtube.com/playlist?list=PLjfRmoYoxpNoaZmR2OTVrh-72YzLZBlJ2 #MATLAB #DigitalSignalProcessing
