Comparison of Methods Based on Discrete Wavelet Transform Used for Filtering of Ultrasonic Signal
Original language description
In ultrasonic testing it is very important to recognize fault echoes buried in noisy signal. The fault echo characterizes flaw in material. To differentiate the fault echo from the noise, a suitable filtering method has to be used. This can be accomplished using discrete wavelet transform (DWT), which is used for enhancement signal-to-noise ratio. In this study for comparison of quality of filtering, DWT and wavelet packets (WP) are used. Additional computer simulations of the proposed algorithms are presented.
