SIGNAL PROCESSING METHODS ON HIGH EFFICIENT DIGITAL RECORDING

High Performance Digital Signal Processing

Recent improvements in the speed and complexity of commercially available digital signal processing (DSP) devices have allowed digital techniques to be extended to a number of new areas. Now many applications in RF and communications are within the bandwidth capability of current generation DSP systems. This paper demonstrates a system developed recently for such applications. It uses standard ...

Digital signal processing methods for biosequence comparison.

A method is discussed for DNA or protein sequence comparison using a finite field fast Fourier transform, a digital signal processing technique; and statistical methods are discussed for analyzing the output of this algorithm. This method compares two sequences of length N in computing time proportional to N log N compared to N2 for methods currently used. This method makes it feasible to compa...

Area Efficient Vedic Multiplier for Digital Signal Processing Applications

This paper proposes a method for area efficient fractional fixed point(Q-format) multiplier based on Urdhava Tiryakbhyam of vedic mathematics. Even though conventional or normal Urdhava multipliers carries high speed mathematical operations, they consume more chip area. Hence we proposed a pipelined multiplier architecture in this paper which consumes less chip area. The pipelined multiplier ar...
