Problem
An electrocardiogram (ECGIEKG) measures signals produced by the polarization and depolarization of the heart for evaluation of heart abnormalities. Frequencies produced by the heart are typically in the range between 0.314 ~ 942.4 radfs. In evaluating your ECG chart, you ?nd that your signal is indistinguishable due to a noise source. To isolate the noise, you utilize an oscilloscope and network analyzer to identify that the noise source spans 376 - 378 radfs and has a signal strength of 10 dB. The actual ECG frequencies are only at a signal strength of 1 dB.
If you require a signal-to-noise ratio (SNR) of at least 10 to accurately measure your ECG, explain how you would remove the noise source and achieve the desired SNR'? (Be speci?c about the requirements and details for your solution).
