Variable digital filters (VDF) find many application areas in communication, audio, speech and image processing. This thesis analyzes design and implementation of FIR digital filters with variable frequency characteristics and introduces two design methods. The design and implementation of the proposed methods are realized on Matlab software program. Various filter design examples and comparisons are also outlilned. One of the major application areas of VDFs is software defined radio (SDR). The interpolation problem on sample rate converter (SRC) unit of the SDR is solved by using these filters. Realizations of VDFs on SRC are outlined and described. Simulations on Simulink and a specific hardware are examined.

Analysis of coupled lines in microwave printed circuit elements Piroğlu, Şefika Özkal; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2007) Full wave analysis of microstrip lines at microwave frequencies is performed by using method of moments in conjunction with closed-form spatial domain Green’s functions. The Green’s functions are in general Sommerfeld-type integrals which are computationally expensive. To improve the efficiency of the technique, Green’s functions are approximated by their closed-forms. Microstrip lines are excited by arbitrarily located current sources and are terminated by complex loads at both ends. Current distributions ...
High performance readout electronics for uncooled infrared detector arrays Yıldırım, Ömer Özgür; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006) This thesis reports the development of high performance readout electronics for resistive microbolometer detector arrays that are used for uncooled infrared imaging. Three different readout chips are designed and fabricated by using a standard 0.6 m CMOS process. Fabricated chips include a conventional capacitive transimpedance amplifier (CTIA) type readout circuit, a novel readout circuit with dynamic resistance nonuniformity compensation capability, and a new improved version of the CTIA circuit. The fabr...
Design and implementation of microwave lumped components and system integration using MEMS technology Temoçin, Engin Ufuk; Akın, Tayfun; Department of Electrical and Electronics Engineering (2006) This thesis presents the design and fabrication of coplanar waveguide to microstrip transitions and planar spiral inductors, and the design of metal-insulator-metal capacitors, a planar band-pass, and a low-pass filter structures as an application for the inductors and capacitors using the RF MEMS technology. This thesis also includes a packaging method for RF MEMS devices with the use of “benzocyclobutene” as bonding material. The transition structures are formed by four different methods between coplanar ...
The implementation of a direct digital synthesis based function generator using SystemC and VHDL Kazancıoğlu, Uğur; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007) In this thesis, a direct digital synthesis (DDS) based function generator design module is presented, defined and implemented using two digital hardware modeling/design languages namely SystemC and VHDL. The simulation, synthesis and applicability performances of these two design languages are compared by following all digital hardware design stages. The advantages and open issues of SystemC based hardware design flow are emphasized in order to be a reference for future studies. SystemC initially appeared a...
Design and Implementation of a Microprocessor Based Data Collection and Interpretation System with Onboard Graphical Interface Göksügür, Gökhan; Güran, Hasan Cengiz; Department of Electrical and Electronics Engineering (2004) This thesis reports the design and implementation of a microprocessor based interface unit of a navigation system. The interface unit is composed of a TFT display screen for graphical interface, a Controller Circuit for system control, a keypad interface for external data entrance to the system and a power interface circuit to provide interface between the battery of the navigation system and the Controller Circuit. This thesis reports high speed design of the Controller Circuit and generation of system fun...
