Yarn periodical errors determination using three signal processing approaches

This paper presents a study developed for identifying the type and location of yarn periodical errors applying three different signal processing approaches based on FFT – Fast Fourier Transform, FWHT – Fast Walsh – Hadamard Transform and FDFI – Fast Impulse Frequency Determination.
