Applications of wavelets in the photoacoustic detection of trace gases with noisy signals
This paper shows that the use of filters based on the discrete wavelet transform (DWT) improves the sensitivity of photoacoustic systems for measurement of trace gases under conditions of unfavorable signal-to-noise ratio (SNR). To achieve this goal, a filter based on Meyer's DWT was designed a...
