Conclusion
The design of low power high performance circuit for solving circular convolution, DFT and Chirp Z-Transformation has been reported in this paper. Our attempt in this work has been to reduce the power consumption, delay and hardware as well as operational complexity of the circuit. We found total delay of this circuit is 2.061ns.
