— Voice enabled applications over the Internet are rapidly gaining popularity. Reducing the total bandwidth requirement can make a non-trivial difference for the subscribers having low speed connectivity. Voice Activity Detection algorithms for VoIP applications can save bandwidth by filtering the frames that do not contain speech. In this paper we(More)
— The complexity of Finite Impulse Response (FIR) filters is dominated by the number of adders (subtractors) used to implement the coefficient multipliers. A greedy Common Subexpression Elimination (CSE) algorithm with a look-ahead method based on the Canonic Signed Digit (CSD) representation of filter coefficients for implementing low complexity FIR(More)
A 12-year-old girl with a 4-year history of effort dyspnea and palpitations was referred to our institution for evaluation. Physical examination of the patient showed a continuous grade 3/6 heart murmur best heard along the right upper sternal border. A two-dimensional echocardiogram exhibited a small interatrial septal defect (diameter, 4 mm) with a(More)
Inferior vena caval thrombosis is an unusual complication of permanent pacemaker implantation. The clinical presentation due to thrombosis depends on the site of thrombus. We have described here a rare case of pacemaker lead associated thrombosis of inferior vena cava, its diagnostic work up and briefly reviewed the existing literature of this uncommon(More)
— Realtime voice communication over the Internet has rapidly gained popularity. It is indeed essential to reduce the total bandwidth consumption to efficiently use the available bandwidth for the subscribers having low speed connectivity and even otherwise. In this paper we introduce a novel technique to identify the voice and silent regions of a speech(More)
