Research ArticleOpen accessIn the keywordsA Three-Microphone Adaptive Noise Canceller for Minimizing Reverberation and Signal DistortionZayed M. RamadanThis paper introduces an adaptive noise canceller (ANC) to improve the system performance in the presence of signal leakage components. The proposed ANC consists of two adaptive filters and three microphones. The first adaptive filter cancels the signal leakage and the second filter cancels the noise. For best results, a least mean squares adaptive algorithm was also introduced and used … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,089 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGate Replacement Technique for Reducing Leakage Current in Wallace Tree MultiplierNaveen Raman, ThanushkodiLeakage power has become more significant in the power dissipation of today’s CMOS circuits. This affects the portable battery operated devices directly. The multipliers are the main key for designing an energy efficient processor, where the multiplier design decides the digital signal processors efficiency. In this study gate replacement technique is used to reduce the leakage power in 4×4 Wallace … …Journal of Computer Science, Vol. 9, Issue 2 · 30 Mar 2013 · 6,763 accessesView PDF Cite
