Wavelets are powerful tools that can be used in signal processing and data compression. They are an excellent alternative to Fourier transforms for applications with transient input signals. There is a large volume of published studies describing the use of wavelets in various fields. However, properties of each family for designs with technology libraries have never been investigated. The present work aims to study the most commonly used wavelets (orthogonal and biorthogonal) and compare the area, speed and power consumption of each family when the designs are synthesized using 150 nm standard cell TSMC library. The aim of this paper is to serve as a convenient reference for wavelet users and reviews.
