Application of wavelet transform in analysis of cough sound records

The work deals with the analysis of a digital recording of cough sounds. This signal was obtained using a digital recorder with a microphone placed on the patient’s chest. The wavelet transform was used in this work. The principle of its operation, various wavelet functions, and types of these functions are described. The core of the work is the continuous wavelet transform algorithm. The source code for the continuous wavelet transform applied to selected parts of the cough sound recording was created and tested in MATLAB.
