Subject: SNR script to run using Matlab

Hi,

I have a problem to run a script for SNR. Here the details.

By using the given signal, the signal should be embended with noise with with different Signal-to-noise ration (SNR) of 0dB, 5dB, 10dB, 15dB, 20dB, 25 dB and 30 dB. Details of the programming should include:
1. How SNR of the noisy signal is calculated
2. Comparison of time domain and Power Spectrum Density (PSD) of original signal, noisy signal and filtered signal for each SNR.

Anyone know how to write script for this SNR using given signal?
