DIGITAL FILTER APPLICATIONS

reduce a certain kind of noise. T Download ‘[login to view URL]’ to your computer from the . After it is unzipped, you should find the following MATLAB files ‘[login to view URL]’, ‘[login to view URL]’, ‘[login to view URL]’ and ‘[login to view URL]’. Tasks 1. ‘ECG_3a’ is an electrocardiogram signal contaminated by a slowly varying noise component. The sampling frequency is 200 Hz. Design a filter that removes the slowly varying component but preserve the shape of the signal components of the electrocardiogram. 2. ‘ECG_3b’ is another electrocardiogram signal contaminated by wideband noise and a sine wave. The sampling frequency is 200 Hz. Design a filtering system to remove noise and recover the original signal. 3. ‘ECG_3c’ is also an electrocardiogram signal contaminated by noise. The sampling frequency is 200 Hz. Design a filtering system to remove noise and recover the original signal. You need two filters. 4. ‘sig_3’ consists of three tone bursts. Each tone burst has a unique frequency. The signal is contaminated by noise. The sampling frequency is 1000 Hz. Design a filtering system to remove noise and recover the original signal. You need three filters. . input and output signals, spectra of the signals, filters that you have designed, descriptions of the action of each filter, and relevant comments or explanations above Your explanations should be clear and accurate such that an educated reader who is not a specialist in this field can understand what you have done.
