摘要:
An automatic recording system for measurements of biological impedances at different frequencies is described. The system comprises a signal synthesiser and a network analyser controlled by a desk calculator. The impedance and phase angle are recorded at one hundred and sixty logarithmically-spaced frequencies between 100 Hz and 1 MHz. A pilot study was conducted to explore the usefulness of the system for investigating fluid balance problems.
