WebNotation, Frequency Variable In each case, the original (time-domain) signal is represented by lower case x– in particular,x(t) in continuous-time andx[n] in discrete-time. The appro- priate Fourier transform in each case is represented by upper caseX. WebThe ECG and ICG measurements allow an approximate calculation of the heart stroke volume. The ECG and the measured impedance showed a high correlation to commercial devices (r=0.83, p<0.05). In addition to commercial devices, the developed system allows a multi-frequency measurement of the thoracic impedance between 5-150 kHz.
