Results of the measurement chain simulations. (a) Resulting changes in ECG signal morphology due to input high-pass filter characteristic over varying coupling capacity $C_{\mathrm{cpl}}$. Different coupling frequencies are represented by different shades of blue from $0.1\mathrm{pF}$ to $0.1\mathrm{nF}$, the original ECG signal is shown in orange. (b) Comparison between original ECG signal morphology and amplitude-aligned filtered signal for the input high-pass characteristic with a cut-off frequency of $f_{\mathrm{c}}=10.6\mathrm{Hz}$.
