Modulation Techniques

Online RF Technology Certification


Besser Associates

This online program has been designed for applications, production, manufacturing engineers and technicians as well as other professionals who need to have a solid background in the fundamentals of working with RF and wireless products. This four part program provides a thorough understanding of RF analytical tools, communications signals, RF devices and test instruments. Starting with basic analytical tools such as the decibel scale, S-parameters and the Smith Chart, this program covers test instrumentation, RF components, and modulation.

Foundations of Green Communications


Earl McCune

Until now, the focus in developing wireless communications formats has been almost exclusively on using novel techniques to overcome specific channel impairments (i.e. multipath, selective fading, etc). What has been missing is an assessment of the overall energy efficiency of the final hardware that is to be deployed. This paper introduces this type of analysis.

FM Modulation Tutorial Applets


Circuit Design Inc. (Japan)

This tutorial and accompanying applet allow you to experiment with FM parameters and see the results at different stages of demodulation. Of particular interest is the applet showing the output spectrum for an adjustable modulation index, based on the values of the Bessel functions for the various sidebands.
