A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...

Abstract: This paper presents an approach for studying the amplitude modulation and demodulation. An algorithm for the laboratory exercise and block diagrams for MATLAB Simulink used in it, are ...

ABSTRACT: The manuscript developed an optimal frequency band transmission system structure of QPSK. The software programming experiment of this complete QPSK optimal band transmission system is ...
