Abstract

The presence of noise in raw signal causes a continuous background signal which sometimes completely takes over the signal from those particles containing low-level charges and as a result, the ability of the sensor to detect charge distribution gets limited. This paper highlights for the first time the use of wavelet transforms to denoise the charge signal to improve the SNR of a charge signal which contains the transient peaks generated as an abrupt change and contains the information of interest. In comparison to the traditional noise reduction method Wavelet transform successfully isolate and minimize the noisy and preserves the shape and quality of the signal while achieving improved SNR.
