A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

The circuit presented here makes amplitude modulation possible, and it also has the significant advantage that it replaces the somewhat exotic and quite expensive OP603AP output opamp with a standard ...

This article discusses the GALANT adaptively steered antenna array and receiver and demonstrates the test scenarios generated with the GNSS simulator. Exemplary results of different static and dynamic ...

What is an RF detector? An RF detector monitors or samples the output of an RF circuit and develops a dc output voltage proportional to the power at that point. What do you do with an RF detector? RF ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...

The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...

Over-the-air (OTA) broadcast television may be making a comeback with major networks now sending HDTV signals capable of being picked up by the humble rooftop antenna. But subscriber TV services from ...

If you want to watch tapes on your VCR or see movies from your older video camera, you may not be able to use your new digital TV. One alternative is to connect the devices to your VGA computer ...

Even a newly installed transmission line is not perfect. You bolt together the new sections properly, install all bullets and tighten all the bolts, but still ...
