Abstract | ||||
ABSTRACT Different kinds of functions are required for today’s Electronics and Communication applications with very precise characteristics like frequency, phase, magnitude and waveform etc. A technique for Field Programmable Gate Array (FPGA) based hardware realization has been developed for the design, implementation and prototyping of useful functions in digital form. The technique makes use of the orthogonal functions like Rademacher and the Walsh functions for the hardware realization. The FPGA based hardware realization of sinusoidal, triangular, and trapezoidal waveforms in their digital form has been demonstrated with good results. A comparative study of hardware realization of such functions targeted to various FPGAs available from Xilinx has been made. It is concluded that virtually any periodic function may be realized directly in its digital form (without the need of Analog to Digital conversion) with the help of FPGAs using orthogonal functions. | ||||
