Abstract: In this paper, design and realization of a 3D printed D-dot type probe is studied for measurement of Electromagnetic Pulse (EMP). D-dot probe is firstly designed in a 3D Electromagnetic simulation tool CST. Next, the 3D modelled probe design is realized with the usage of 3D printing technology and its experimental performance is measured. The 3D printed D-dot probe prototype is tested in accordance with the requirement of RS105 test using an EMP generator and a GTEM cell. The experimental results of the proposed 3D printed D-dot probe then are compared with a counterpart commercial probe and it is found that the response of both probes are have similar characteristics for the EMP signal. Thus it can be concluded that the proposed method is a prototyping method for the EMP probes of the desired level in a fast and cost efficient ways.

Abstract: This Paper Presents a comprehensive investigation of the RF Signal Strength of Love FM Transmitter in Port Harcourt, Nigeria. The Signal measurement were carried out at different locations with the aid of a GPS band scanner. A maximum distance of 6KM was chosen with respect to the North, South, East and West of the Transmitter. The measuring points have interval of 1km from each other, summing up to 24 different measuring points. The result of the measurement was used to plot the attenuation decay curve of Love FM Radio station's transmitting antenna. The personal computer used for the exercise displays the outputs and results such as the Distance, electromagnetic.......

Abstract: Shift registers plays a vital role in many of the digital systems. They are used to store binary information and this binary data can insert or shift using flip flops. By the use of sequential I/O channels shift register plays an important link between systems.With the downscaling of chip size in VLSI technology, the prime factor to design any circuit is power dissipation. This work enumerates implementation of PISO & PIPO shift register by master slave D flip flop as a storage element using BICMOS logic. Cadence EDA tool has used to design proposed shift registers at 180nm technology. Supply voltage is varying between 1.2 to 2v and frequency of clock signal is 200MHz. Results of power dissipation for the proposed shift registers have compared with the results of conventional design using CMOS technology, which clearly shows that proposed circuits have less power dissipation compared to conventional circuits
