Abstract
A method for determining impedance includes receiving a time varying voltage signal from a biosensor and receiving a time varying current signal from the biosensor. The time varying voltage signal and the time varying current signal are transformed to a domain that represents complex impedance values. Parameters based upon the impedance values using at least one of an explicit decimation process and an implicit decimation process.
