In this problem, we want to study the effect of an averaging filter (averaging window) on eliminating the noise on a signal. Use MATLAB to generate a 10 periods of a discrete sin wave signal with amplitude=1 and period = 50 samples. Then add Gaussian noise to it with amplitude 0.1. Pass the noisy signal on an averaging filter of variable length. PLOT the original signal, the noisy signal, and the filtered one. What is the effect of the filter’s length? What happens if the filter’s length becomes too small or too large? Helpful MATLAB keywords conv, plot, randn, hold

Oh, come on. MAKE AN EFFORT. Don't just post your problem and plead for code. You will never learn a bit that way, beyond how to get someone else to do your work for you!

But if you don't have much time, then you need to learn to manage your time. I'm sorry, but your emergency is not ours. Your emergency merely means you need to do a better job with your time. Start working on your problems immediately, not when they are due.
