Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

For the PDF version of this article, click here. This article will present three methods for using synchronous amplitude-modulated magnetic feedback for controlling dc-dc converter output voltage ...

This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...

As Radio World has reported, the FCC recently made it easier for AM stations to use modulation-dependent carrier level systems to save money on their transmitter power bills. Our website recently ...
