systems increasing year by year. This results in the on demand for scaling and integration with the help of advanced CMOS technologies. Soft errors are reliability thread on modern digital world which explains the need of protection against errors in digital circuit applications. In some applications, techniques like Algorithm based fault tolerance (ABFT) are used to detect and correct error with the help of algorithm properties. As the filters are the basic building blocks in most of systems, FFTs are used with the protection scheme using parseval checks which detects and corrects errors. The proposed technique consume low power. A technique is proposed using parseval checks to protect the circuits from single bit errors and is further improved for multi bit errors detection and correction and are evaluated in area and delay parameters
