This paper addresses the experimental study of the wide band signal estimation and reconstruction using the established compressive sampling (CS) methods. For this purpose, a hardware test bed was setup inter-connecting a wide band SDR based hand held military radio (SWAVE HH or HH), vector signal generator, bi-directional coupler, attenuators, PC and other auxiliaries. Real-world communication...

This article is related to the experimental data regarding the ability of MRET Noise Field Generator (MRET NFG) placed at the distance of 7 feet from “phantom head” exposed to RF phones radiation to reduce specific absorption rate (SAR) of the water based solution inside “phantom head”. The core part of Generator is MRET polymer compound. Due to the fractal geometry structure of MRET polymer co...

We introduces a new method that can achieve the generation of Colpitts chaotic signal The system is based on virtual instrument platform and combined with MATLAB calculation to achieve the generation of Colpitts chaotic signal and making it analysis with autocorrelation and power spectrum at the same time. Signal channel output of chaotic signal was realized through USB-6009 acquisition module ...

In this paper, we present an ultra-wideband (UWB) pulse generator based on the step recovery diode. The principle of operation and the architecture of the developed pulse generator are explained. Furthermore, hardware implementation issues and the details on the generated UWB pulse including its peak voltage equal to 8.9 V, its full width at half maximum (fwhm) equal to 240 ps, and frequency sp...

This work is aimed at the development, research and optimization of superconducting integrated circuits designed to match impedances a long Josephson junction generator, so-called flux generator (FFO) superconductor--insulator--superconductor (SIS) detector in sub-terahertz frequency range. Numerical calculations optimize parameters transmission lines are presented. The main their influence on ...

Abstract Preparing experiments that utilize free electron lasers is challenging because obtaining access to the facility difficult. The integration of detectors into data acquisition system needs be tested before beamtime starts. In this study, we develop a test signal generator simulates signals from delay-line detector used in time-of-flight spectrometer. output simulator are connected time-t...
