I have provided the coding for part a and b All I need the PLOT GRAPH IMAGE with the correct lables. I will rate if provided what I asked for.A lot can go wrong when recording a patients ECG. If the electrode patches on the skin are not sufficiently conductive, then the measured signal will be poor. If the patches are placed in the wrong locations, then the amplitude of the signal may be too small to be of any value. Alternatively, if the patches are placed in opposite locations, the signal will be flipped upsidedown. Understanding how best to correct for these and other challenges will improve your ability to diagnose and process any sort of signal, biological or otherwise.
You are provided with a poorquality ECG recording that is stored in the data file named badECG.txt which you can download from Canvas. The sampling rate is Hz for three seconds. The data is poor in these ways: there is an unwanted DC offset, the data is flipped upsidedown, and the recorded signal level is too low.
a Your task is to write a new script that reads badECG.txt and processes the poor signal data into something that looks more like a good ECG. Do this by performing the following:
o Remove the DC offset
o Invert the waveform
o Proportionally amplify the signal so that the highest peak is approximately at the mV level
b On the same fully labeled graph, plot both the original bad signal and your improved signal versus the time not index You need to show the full three seconds of recorded data on the graph.
