Algorithms for calculating the discrete wavelet transform for processing such signals are proposed and their choice is justified depending on the task. A study of the main prospective directions of using the time-frequency, wavelet area of transformation and signal processing for various areas of application, namely for filtering non-harmonic, non-stationary signals and their compression, as well as applying digital signatures (watermarks) to various multimedia products. It is shown that the wavelet of signal transformation can be effectively used for diagnosing defects and predicting possible breakdowns of responsible parts of mechanical systems. A method of using the wavelet domain to estimate the integral characteristics of broadband signals is proposed.
