As real time signals change continuously, adaptive filtering is required for noise cancellation. An adaptive filter is one whose characteristics can be modified by adjusting its parameters according to an optimization algorithm The adaptive filtering operations can be implemented as a sequence of logic operations on a Digital Signal Processing (DSP) chip,Gate Arrays such as FPGA or Application Specific Integrated Circuits. There is always a tradeoff in the parameters area, power and speed in VLSI. This paper provides the implementation of adaptive LMS Filter using different types of multiplier and its analysis for the various parameters. The LMS Filter is designed using conventional array multiplier, Computation Sharing Mutliplier(CSHM) and Karatsuba Vedic Multiplier. The results show 70% reduction in delay and 19% reduction in area on using Karatsuba Vedic Multiplier ofr adaptive filter design.
