Abstract
Low crest factor (CF) multi-sine can bring high signal-to-noise ratio for fast frequency response function (FRF) measurement. This paper synthesizes a broadband multi-sine signal which has 15 flat and quasi-logarithmically spaced spectrum and a low CF of 1.8484. The multi-sine is realized based on a field-programmable gate array (FPGA). The generated multi-sine has the fundamental frequency of 8 kHz, and spans logarithmically from 8 kHz to 800 kHz at its 15 harmonic components. This paper provides an applicable solution to synthesize and generate broadband multi-sine signals.
