Book Description

The textbook, Introduction to Wavelet Transforms provides basics of wavelet transforms in a self-contained manner. Applications of wavelet transform theory permeate our daily lives. Therefore it is imperative to have a strong foundation for this subject.


  • No prior knowledge of the subject is assumed. Sufficient mathematical background is provided to complete the discussion of different topics.

  • Different topics have been properly segmented for easy learning. This makes the textbook pedagogical and unique.

  • Notation is generally introduced in the definitions. Relatively easy consequences of the definitions are listed as observations, and important results are stated as theorems.

  • Examples are provided for clarity and to enhance reader's understanding of the subject.

  • Each chapter also has a problem section. A majority of the problems are provided with sufficient hints.

The textbook can be used either in an upper-level undergraduate or first-year graduate class in electrical engineering, or computer science, or applied mathematics. It can also be used by professionals and researchers in the field who would like a quick review of the basics of the subject.
