Abstract:

A method is provided for determining segmented partition capture area by using a minimum detectable signal and a maximum interfering signal calculated from a driving point impedance. A signal channel of an analog-to-digital converter is selected and then a signal channel of a low-noise amplifier is selected in order to reduce the noise for the system using the method. The maximum value of the analog-to-digital noise and the minimum value of the analog-to-digital converter input signal sinewave signal are determined. The signal channel is designed by the use of a channel noise figure, a channel full scale input signal and a channel input impedance. A maximum interfering signal is defined by the channel full scale signal to set a limit on the segmented partition capture area.
