I have long been an advocate of AM bandwidth restriction to approximately 5 kHz — long before the recent trend and well before digital IBOC and/or DRM came on the scene. The genesis for my advocacy ...

Abstract: Detailed knowledge of time dispersion characteristics of radio multipath propagation channel is essential for successful design of ultra-wideband (UWB) systems. The multipath-clustering ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...

Also known as 802.16-2004, WiMAX probably is the only wireless standard that allows for bandwidth changes to better match up with the available spectrum and the desired speed partitioning for ...

One of the most hotly contested bits of real estate today is one you can't see. As we move into an increasingly wireless-connected world, staking out a piece of the crowded electromagnetic spectrum ...

Rohde & Schwarz’ CMA180 radio test set, designed for analog-radio production and maintenance, can generate any test signal up to 20-MHz bandwidth and process input power levels up to 150 W. Rohde & ...

Automakers attempting to remove AM radio from vehicles has been an ongoing and bizarre battle. Companies want it gone due to claims that the bandwidth can interfere with the newer tech equipped to ...
