Automatic Speaker Recognition technology has recently been implemented in large number of commercial areas successfully. Speaker recognition is being used in voice based biometrics; voice controlled appliances, security control for confidential information, remote access to computers and many more interesting areas. This paper introduces text dependent… (More)
Contactless smartcards are widely used in transport systems, banking systems, identify cards etc. More and more data and operations are being stored and performed in the contactless smartcards, but the power acquired from the reader is limited. To allow more operations to be performed in the cards, the asynchronous circuit technique that promises lower… (More)
Human body channel, a candidate of PHY layer adopted by the latest IEEE standards (IEEE 802.15.6), has been investigated for applications with on-body communication. The study covers frequencies range from 100Hz to 1GHz and channel lengths from 65mm to 1.6m. After analyzing the measurement results, a suitable frequency range for body area network from 10… (More)
Speech recognition system needs to perform a high complex calculation and short time to complete it. This is a big challenge for the real-time systems. However, using a simple and fast algorithm may do this task for the slow systems. Thus, the main objective of this paper is to design and implement a Real-Time Arabic Speech Recognition system using MATLAB… (More)
This paper presents the design and measurement results of a sub-1 V, wide-tuning range, monolithic voltage-controlled oscillator (VCO). The LC-based VCO can operate at a supply voltage as low as 0.8 V. The top-biased PMOS, with capacitor connected in parallel, is used in order to decrease the noise contribution in the oscillated frequency even at a low… (More)
SUMMARY Detecting the stuck-at-pass faults in the event-driven latches is the main difficult in testing latch based asyn-chronous pipeline. In this paper we proposed a parallel test structure to ease this problem.
