iii ACKNOWLEDGEMENTS I would like to express my sincere gratitude to my thesis supervisor, Prof. Avni Morgül for his invaluable guidance, patience, motivation, advice and contributions throughout this study. His guidance helped me in all the time of research and writing of this thesis. It was really a pleasure for me to work with him. I would like to thank(More)
A novel algorithm for full-addition of two signed, higher-radix numbers is proposed and implemented by combining multi-valued logic min, max, literal and cyclic operators. Owing to disjoint terms involved, multi-valued logic min and max operators are replaced with ordinary transmission operation and sum, respectively. A multi-valued logic cyclic gate is(More)
The multi-valued logic circuits provide very small chip size, higher speed, and a small number of interconnections. However, the main drawback of these circuits is the lower noise margin and it is necessary to restore the nominal levels of the signal after a certain number of cascaded stages. A new current-mode CMOS restoration circuit is presented and(More)
— Adder trees are the crucial design blocks of many arithmetic VLSI circuits. Alternative implementations can solve the large area requirements and complicated interconnection scheme of these building blocks. Multiple Valued Logic (MVL) implementation of an adder tree can be an alternative design style, which can save from area and interconnect. I.(More)
In this study, the reflected signal from the ionosphere in monostatic HF surface wave radar system is investigated in terms of atmospheric attenuation and Doppler spectral dispersion, by Chapman distribution and auto-correlation function when the process is stationary and time variant, respectively. The model-based analysis shows that doppler dispersion(More)
