Abstract :
The fast Fourier transform (FFT) and digital filter design are two basic parts of digital signal processing (DSP). Combining FFT and filter design, this paper proposes a mode shape testing method based on data acquisition, analysis and processing. In addition to these, the paper takes a simple-supported beam as an example to validate the method and achieves a satisfactory result.
