Abstract
A novel switched-capacitor discrete Walsh transform circuit is proposed. The Walsh hardware transformation is improved in simplicity by using the proposed circuit, and this circuit has a speed advantage because of analog processing. Furthermore, a switched-capacitor inverse Walsh transform circuit is constructed. A switched-capacitor sequence filter is also proposed which combines the Walsh transform circuit and its inverse.<>
