A system and method for determining physiological parameters based on electrical impedance measurements is provided. One method includes obtaining electrical measurement signals acquired from a plurality of transducers coupled to a surface of an object and spatially pre-conditioning the obtained electrical measurement signals. The method also includes performing multiple-input-multiple-output (MIMO) processing of the spatially pre-conditioned electrical measurement signals to correlate the spatially pre-conditioned electrical measurement signals to separate the electrical measurement signals.

Methods for determining physiological parameters based on electrical impedance measurements

A system and method for determining physiological parameters based on electrical impedance measurements is provided. One method includes obtaining electrical measurement signals acquired from a plurality of transducers coupled to a surface of an object and spatially pre-conditioning the obtained electrical measurement signals. The method also includes performing multiple-input-multiple-output (MIMO) analog to information conversion (AIC) of the spatially pre-conditioned electrical measurement signals to correlate the spatially pre-conditioned electrical measurement signals to separate the electrical measurement signals.

System and method for determining physiological parameters based on electrical impedance measurements

An analog-to-digital converter (ADC) is provided includes a first sigma-delta modulator (SDM) electrically coupled to a first signal input. The first SDM includes a first summing junction configured to receive a plurality of inputs to the first SDM. The ADC further includes a second sigma-delta modulator (SDM) electrically coupled to a second signal input. The second SDM includes a second summing junction configured to receive a plurality of inputs to the second SDM. The first SDM also includes a cross-coupled feedback loop from an output of the first SDM to a negative input of the first summing junction and to a positive input of the second summing junction. The second SDM also includes a cross-coupled feedback loop from an output of the second SDM to a negative input of the first summing junction and to a negative input of the second summing junction.
