The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

I needed to test a UHF linear amplifier’s ability to deliver a low distortion AM signal output. Unfortunately, the output distortion requirement was better than the distortion limits of any commercial ...

“Diode Modulation” is a simple means of creating an AM signal. The exciter creates the carrier. Audio is combined to create amplitude and sidebands and then sent to a half-wave rectifier. This signal ...

Amplitude modulation, or AM, is probably the simplest method of getting a voice or some music onto a radio signal and then sending that signal off to some far distant place. Because of that simplicity ...

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 ...
