Abstract

Multisine excitation is widely used in impedance measurements to retain the advantages of the sine wave, while reducing the measurement time. To keep the crest factor (CF) of the excitation signal low, the initial phases of the signal components must be optimized. This paper focuses in further optimization of multisine signal for improving the signal-to-noise ratio (SNR) of measurements, reducing the complexity of signal generation and minimizing a memory footprint of the FPGA based implementation.
