How radios send and receive information can seem magical to the uninformed. For some people, this week’s Retrotechtacular video, “Frequency Modulation – Part 1 Basic Principles”, from the US Army ...

The table below allows you to easily determine the modulation level of an AM transmitter. Connect an RF sample to the horizontal input of an oscilloscope and set the peak-to-peak (pk-pk) unmodulated ...

When broadcasting was in its infancy, amplitude modulation (AM) was the principal modulation system being researched and developed. Once efficient generation of useful RF signals was discovered and ...

Who says AM radio is passé? Inovonics has sped up its market launch of its new 526 AM Modulation Monitor, and shipping has now commenced. Inovonics was expected to begin shipping the 526 in May. Gary ...

To understand the difference between AM and FM, it’s first important to know how radio stations – which still use traditional broadcasting methods – get the music to our stereos. Stations start off ...

Abstract: This article focuses on taking the STM32F407ZGT6 single-chip microcomputer and the four-channel DDS AD9959 as the core. Combined with the serial port screen, the modulation degree and ...
