digital signal processing problem

Q1. The file LabECG.csv was taken from an oscilloscope reading. The first column is time values and the second column is magnitude values. Sampling frequency was 2.5 kHz. Magnitude is 100 mV scale.

a. Create a plot of the ECG graphed in time with all axis labeled accordingly.

b. An analog notch filter was made to filter out AC power interference. Based on the data, did the analog notch filter work? How do you know?

c. The ECG data is contaminated by noise. Apply proper methods to obtain a clean ECG signal.

You didn't ask us a question. You know, you can. Just read this first:

How do I get help on homework questions on MATLAB Answers? - MATLAB Answers - MATLAB Central

In the meantime, a hint is to look up readmatrix(), plot(), xlabel(), ylabel(), and fft() in the help documentation. When/if you come back, make sure to post your attempt at code and attach your m-file. A screenshot is fine but if we're to run code, we need more than a screenshot -- we need an m-file.

yep !

we're here to help but not to do the homework for you
