The patch - Snap on electrode that is connected to the body via a conductive gel in ECG measurement is modelled as: 10 K to 2 Megohm 50 to 200 ohms O 10 to 50 nfd Figure 1. Human Tissoe-Electrolyte- Electrode Model lead wire Find the impedance of this system as a function of frequency when the values of 100 ohm, 15k and 50 nF are used for the model. Show work. Use Matlab to plot the system transfer function over the frequency range of DC to 100 KHz. Procedure: 1. Capacitance in 's' domain. 2. Parallel combination of 15k and the Capacitor in series with 100 ohm. This is H(s) 3. In Matlab, create a transfer function using sys-tf(num coef, den coef) 4. Use built in function Bode to plot the magnitude and phase of the system transfer function. Is this electrode/electrolyte interface impedance large or small in the ECG frequency range?
