Abstract
Orthogonal functions/transforms such as Rademacher functions and Walsh functions find extensive use in Scientific and Engineering applications. Software realization of such functions has been common for quite some time. However, hardware realization has distinct advantages and is now feasible and economically viable due to advancements made in the Microelectronics technology. Rademacher functions and Walsh functions have therefore been realized using high level design techniques targeted to Xilinx FPGAs. The application of these functions in generating digital and analog sinusoidal waves on the same chip has been demonstrated.
