Denoising filters are used to remove various types of noise from images, signals, and time-series data for the purpose of preserving relevant data. One-dimensional signals benefit from denoising filters which enhance their quality by applying a numerical computation to segments of the signals. A variety of denoising filters exist, such as the median filter, moving average filter, Savitzky-Golay filter, and wavelet transform, which all provide a unique approach to signal-to-noise ratio improvement. This paper provides a direct comparative analysis of these filters' conceptual and practical applications determining which technique will produce the most effective results in signal denoising. Research was conducted using an experimental dataset based on dual-mode scramjet (DMSJ) emissions with the goal of improving engine efficiency at high speeds and preventing harmful events like "unstart."To evaluate the filters' effectiveness a comparison was conducted on the basis of the statistical parameters of Signal to Noise Ratio (SNR) and Mean Square Error (MSE). This showed the moving-average filter and the wavelet transform method served as the top performing. Further evaluation was conducted to distinguish between the steady states and transition states of our denoised signals for DMSJ engine improvement using machine learning classifiers. Wavelet transform and the median filter proved to be the most effective in measuring model accuracy and the classification rate of the various classes within our single-step transient data. Our CNN-LSTM hybrid model was also successful in performing classification for our multi-step transient data, resulting in high model accuracy and precision.
