A complete software-based IF GNSS signal generator for software receiver development
free download

The recent development of Global Navigation Satellite Systems (GNSS) software receivers has brought a new perspective to receiver design. The first step necessary to use them is to have access to sampled data at an Intermediate Frequency (IF). These sampled data can be

Sinusoid signal generator for on-chip impedance spectroscopy
free download

Compact signal generators are a necessary component for many biomedical and chemical sensor microsystems. This paper presents a signal generator with precise digital frequency control that is 62% smaller the previous designs. The signal generator can produce analog

Frequency stabilized GaP continuous-wave terahertz signal generator for high-resolution spectroscopy
free download

We constructed a GaP continuous-wave terahertz (CW-THz) signal generator based on different frequency generation that can tune automatically from 0.15 to 6.2 THz without mode- hopping. Independent frequency feedback control for the seed laser and power feedback Nowadays, voltage transducers in medium-voltage (MV) distribution networks operate in nonsinusoidal conditions while their calibration is still based on simple sine-wave tests. A more significant characterization could be achieved using complex multitone signals

Implementation of Digital Chaotic Signal Generator with an Efficient Cross-Correlation in Wireless Communications
free download

This paper describes the digital chaotic signal with ship map design. The robust digital implementation eliminates the variation tolerance and electronics noise problems common in analog chaotic circuits. Generation of good non-repeatable and nonpredictable random

ECG signal generator based on geometrical features
free download

Electrocardiograms are widely used in biomedical signal processing to diagnose abnormal heart functioning. Many algorithms have been constructed to analyse, measure and compress these signals. These methods are hard to test because real ECG signals are

Hybrid GPS/Galileo/GLONASS IF software signal generator

ABSTRACT A Global Navigation Satellite System (GNSS) signal simulator is a necessity for the development and validation phases of a GNSS receiver. By connecting the simulator to the antenna port of a receiver, the latter can navigate as if it is on a real vehicle. Indeed

Advanced Audiometer: A Novel Signal Generator Technique
free download

Audiometry is the technique to identify and quantitatively determine the degree of hearing loss of a person by measuring his hearing sensitivity, so that suitable medical treatment or one of the appropriate hearing aids and assestive device can be prescribed. In audiological

Signal Generator Based on Direct Digital Synthesis Techniques
free download

This paper describes a design of signal generator based on direct digital synthesis technique (DDS). According to the basic principles of DDS using Matlab/DSP Builder establish DDS model, then compiling by the SignalCompiler tools and generating VHDL ELECTROENCEPHALOGRAM (EEG) and other biological signals have random amplitude variations and it is useful to be able to generate a signal having similar properties and that can be repeated exactly. Such a signal is often more appropriate for testing analysis

Development of Real-Time signal generator Graphical user Interface using MATLAB 6.5
free download

Real-time application using MATLAB is very difficult to be implemented since the implementation requires very long and tedious programming code. This paper presents an approach to design real-time signal generator system that uses Graphical User Interface
