## Description

Practical Python Wavelet Transforms (II): 1D DWT is a 1D discrete wavelet transform tutorial published by Udemy Online Academy. Wavelet transform (WT) or wavelet analysis is probably the newest solution to overcome the shortcomings of Fourier transform (FT). Wavelet transform (WT) transforms a signal in period (or frequency) without losing time resolution. In the field of signal processing, wavelet transform (WT) provides a method for decomposing an input signal of interest into a set of elementary waveforms, i.e. wavelets, and then analyzing the signal by examining the coefficients (or weights) of these wavelets. So, if you can learn this great tool, it will be great for your future development.

Wavelet transform can be used for stationary and non-stationary signals such as removing noise from signals, trend analysis and forecasting, detecting sudden discontinuities, abnormal change or behavior, etc., compressing large amounts of data, encoding data, i.e. Use data security and combine it with machine learning to improve modeling accuracy. In this training course, you will learn the concepts and processes of single-level and multi-level 1D discrete wavelet transforms through simple and easy diagrams and examples and two cases and real-world practice. After this course, you will be able to decompose a 1D time series signal into approximate and detailed coefficients, reconstruct and reconstruct the signal, reduce noise from the data signal, and visualize the results using beautiful figures. .
