Multipliers are the most commonly used elements in today's digital devices. In order to achieve high data throughput in digital signal processing systems, hardware multiplication is the important factor. Depending on the applications which are emerging with the electronics devices, various types of multipliers are emerged. Among all the multipliers, the basic multiplier is Array Multiplier.

PCM Codec is a versatile device containing of both transmitter and receiver. Transmitter section consists of low pass filters, sampler, quantizer, encoder and the receiver consists of inverse quantizer, decoder, and low pass filters. 4th order filters are used for avoiding the noise in the signal. In this paper, 4 channels are used, only one channel is working at a time, during this period remaining...
One of the most important processes in smart antennas, is beam forming. The major function of beam forming is to change the beam pattern of the antenna for a given angle. If the antenna does not change its direction based on the receiving signal, the signal losses will be high. So, in order to increase the efficiency and to reduce the signal losses in the system, here a new method is proposed for...
A comprehensive assessment of valvular incompetence remains as an important goal in clinical cardiology now a days. The precise measurement of regurgitant volume in patients with mitral regurgitation is significant for evaluating the progression of the disease which can then determine the optimal time for surgical repair or replacement. This paper portrays color space conversion and anisotropic diffusion...
