The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

Here’s a question: when did you last listen to an AM radio station? If your answer is “recently”, chances are you are in the minority. You might ask: why should you listen to AM? And you’d have a ...

Radio Control /Remote Control and ASK (Amplitude Shift Keying) /OOK (On /Off Keying) have been around for some time, but there is limited coherent information on the subject and the associated ...

A 28GHz time-division multiple-input multiple-output (MIMO) receiver with eight radio frequency elements, each occupying just 0.1 mm, has been developed using 65nm CMOS technology. This innovative ...

In many ways, high-speed optical communications are following the path that wireless technology has blazed. Of course, optical and wireless networks use different technologies to deal with specific ...

A team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

ACCOEDING to a recent report by the New York Correspondent of The Times, a new type of wireless transmission and reception will be used in an experimental station now being erected at Columbia ...

WHAT IS CARRIER PHASE? The obvious answer is: the phase of the carrier. But this is not helpful if you don’t know what a carrier is. A carrier is basically a harmonic electromagnetic wave — a pure ...
