Filter plays an important role in communication systems. It is an electronic device that allows signal in certain frequency ranges to go through. In other words, filter helps remove all the unwanted frequency components in a signal. Generally, there are four types of filters: lowpass filter, highpass filter, bandpass filter and bandstop filter. Two filters have been proposed in my project. The ...

We propose a novel approach for designing a low power datapath in wireless communication systems. Especially, we focus on the digital FIR filter. Our proposed approach can reduce the power consumption and the circuit area of the digital FIR filter by optimizing the bitwidth of the each filter coefficient with keeping the filter calculation accuracy. At first, we formulate the constraints about ...

the impulse response can be either finite or infinite. The methods for designing and implementing these two filter classes differ considerably. Finite impulse response (FIR) filters are digital filters whose response to unit impulse (unit sample function) is finite in duration. This paper presents the design of low power FIR filter and area efficient parallel linear phase FIR digital filter. Lo...

Low Multipliers and Adders are used to reduce dynamic power consumption of a Digital Finite Impulse Response (FIR) filter. These methods include low power serial multiplier and serial adder, combinational booth multiplier, shift/add multipliers, folding transformation in linear phase architecture and applied to FIR filters to reduce power consumption and Distortion is also reduced. The proposed...

In this work a new control strategy for simulation of three phase power filter for power quality improvement is used .This filter consists of shunt passive LC power filter and series active filter, with nonlinear and linear loads and also with variation in the source impedance. A new control method based on dual formulation of instantaneous reactive power vectorial theory is applied by consider...

The aim of this paper is to introduce power idealization filter topologies with respect to filter topologies and power ideals of lattice implication algebras, and to investigate some properties of power idealization filter topological spaces and their quotient spaces.

This paper presents a novel method of hardware reduced fast FIR filter structure for parallel data processing.In general, arithmetic operation modules such as adder and multiplier modules, consume much power, energy, and circuit area. The power consumed by the adder structure is also very significant while designing a low power filter. The proposed low power multipliers and low power adders are...
