Abstract— This paper presents the comparisons between time-domain voltage and current measurement techniques for interference analysis in Power Line Communication (PLC) application. Voltage measurement is performed by directly sensing the mains voltage from a speed-controlled water pump using a 1:1000 voltage divider, whilst the current is measured...

This paper presents the impact of LED lamps on the performance of Narrowband Power Line Communication (NB-PLC) in the CENELEC-A band between 9-95 kHz. NB-PLC in is only one of the many victims of interference in the frequency range 2-150 kHz. Only few emission standards for this frequency range are available, while the number of interference cases...

In this paper, the development of automatic VSAT antenna pointing system based on AVR microcontroller is presented. The system consists of ATMega128 microcontroller as the main controller unit (MCU). User interface is implemented using android smartphone via bluetooth connection with HC-05 bluetooth module for communicating the MCU with the android...

A utilization of split ring resonator (SRR) for developing compact narrowband microstrip bandpass filter (BPF) is presented. The proposed BPF is intended to work at center frequency of 880MHz implementable for intermediate frequency (IF) radar application. The BPF is designed on a 1.9mm thick Roger RT/Duroid® 6010 dielectric substrate with the subs...

Filter in telecommunication is a device which has function as a frequency band selector. They are supposed to pass the desired frequencies and block or suppress the unwanted ones. Filter has been used widely especially in radar system. There are various methods to design a bandpass filter especially for higher frequency. Microstrip filter type is c...

In this paper, we propose a smart home platform based on optimized wireless sensor network (WSN) protocol and scalable architecture. In this platform, system environment is divided into two main environments, indoor and outdoor. Outdoor environment uses internet-cloud system, while indoor environment uses WSN system. This scheme is also well known...

A development of antenna measurement tool for student experimentation is proposed based on AVR microcontroller as main controller unit (MCU). The system of antenna measurement tool is expected to be low-cost and easy-to-use to overcome the problem in cost and complexity of the commercial tool. The proposed system which uses an AVR ATMega8535 as an...
