Notch Filter to remove noise from an ECG Signal
This experiment is based on a question at the Lab Exam (EN1093).
According to the following difference equation which relates output (y[n]) and input (x[n]) we were asked to derive the transfer function H(z). This filter removes the 50Hz noise component.
