Kramers-Kronig (KK) equations allow us to obtain the real or imaginary part of linear, causal and time constant functions, starting from the imaginary or real part respectively. They are normally applied on different practical applications ...
Bandwidth and Common Mode Optimization for Current and Voltage Sources in Bioimpedance Spectroscopy [0.03%]
生物阻抗谱法中电流源和电压源的带宽及共模优化
Tobias Menden,Jascha Matuszczyk,Steffen Leonhardt et al.
Tobias Menden et al.
Bioimpedance measurements use current or voltage sources to inject an excitation signal into the body. These sources require a high bandwidth, typically from 1 kHz to 1 MHz. Besides a low common mode, current limitation is necessary for pat...
Improved Estimation of Left Ventricular Volume from Electric Field Modeling [0.03%]
基于电场模拟的左心室容积计算方法研究与改进
