In practical embedded implementations of the discrete Fourier transform (DFT), used for example in bio-impedance and electrical network analysers, simplification of the solution (to have a low-cost and power-efficient devices) is a vital task. It is shown, that for calculating of few output points of DFT (up to 10-20 points), a modified ldquobasic DFTrdquo can be more efficient than fast and so-called...
Multifrequency vector impedance measurement can be used for bio-impedance analysis, and in many other test and measurement applications. Computationally, efficient digital signal processing algorithm for multifrequency vector impedance measurement uses the synchronous under-sampled discrete Fourier transform (DFT). The main practical problem arising from this approach is significantly high noise level,...
