Use the Harr wavelet:

7- Use Haar wavelet (Averaging and differencing) to expand the given array i-Expand the given array using Haar wavelet into approximation and details input array = 16 14 12 22 17 27 22 14 15 19 10 16 11 9 11 21 11- denoise using hard threshold of details =1. iii-denoise using soft threshold of details=1 iv- find the RMSE between the origianl and the hard and soft denoised signals. RMSE of hard threshold A36 RMSE of soft threshold 7- Use Haar wavelet (Averaging and differencing) to expand the given array i-Expand the given array using Haar wavelet into approximation and details input array = 16 14 12 22 17 27 22 14 15 19 10 16 11 9 11 21 11- denoise using hard threshold of details =1. iii-denoise using soft threshold of details=1 iv- find the RMSE between the origianl and the hard and soft denoised signals.
