Card payment systems mean three elements: credit cards, ATM and EFT POS terminals. ATM. ATM is primarily a device for predominantly cash withdrawals. The presence of these devices has made the cash available 24/7 but at the same time contributed to the cash still remains the most common payment instrument. There are a lot of manufacturers of software packages necessary for their work. This paper analyzes their representation in Central and Eastern Europe, which includes the Serbian. © 2012 IEEE.

Card payment systems mean three elements: credit cards, ATM and EFT POS terminals. ATM. ATM is primarily a device for predominantly cash withdrawals, but also provides many other services to cardholders. Central and Eastern European countries have very uneven level of development of payment card sector. This paper analyzes the state of development of ATM networks in relation to various parameters in the region of Central and Eastern Europe and Serbia. © 2012 IEEE.

This work describes a new type of a phase shifter based on the recursive phase locked loop (PLL) of the second order. This PLL is described by recursive equations. It represents a new approach to PLL. Although this PLL can be used for different applications, the main emphasis is given to the phase shifting of pulse rate. The region of parameters for the stable system and the other analyses of PLL are made using the Z transform approach. Computer simulations of PLL enable better insight into the PLL properties and confirm the mathematical analyses too. The realization of PLL is described. The oscilloscope picture of the input and output pulse rates, recorded on the realized PLL is presented. © 2014, Editura Academiei Romane. All rights reserved.

This paper describes one recursive model of the Phase Locked Loop (PLL) of the second order based on the measurement and processing of the time difference between the input and output periods. The stability and the other conditions, under which the described system can have the properties of a PLL, are investigated using the Z transform analyses. Computer simulation of PLL is introduced in order to give better insight into the PLL characteristics and to confirm the mathematical analyses too. Made analysis shows that PLL is suitable for the wide range of applications. For the corresponding system parameters, PLL possesses the power noise rejection ability. For some other system parameters this PLL possesses the power tracking ability. It can also be used for the measurement of the period of the input signal in the noise environment. The oscilloscope picture of the input and output signals recorded on the realized PLL is presented.

The hardware and software solution of the virtual multisensors data acquisition and analysis system, intended for more laboratory setup is described in this paper. The system uses recently developed digital and analog integrated sensors for acquisition of temperature, relative humidity, ambient light level and atmospheric air pressure. The system also calculates and displays the pressure altitude and the kind of the light as well as depicts the dew-point waveform. Communication between the acquisition hardware and PC is established via USB port of the PC or precisely by emulating RS232 over USB. At the same time the power lines of the USB port serve as power supply lines of the acquisition hardware. Due to the precalibration of the recent sensors, expensive system calibration procedures are avoided and thus the cost of the system maintenance is reduced. The graphical user interface (GUI) is realized under LabView 7 Express integrated development enviroment.
