Wireless high-speed data communication using terahertz (THz) carrier frequencies is becoming reality with data rates beyond 100 Gbit s –1. Many of the mobile applications use internet access and ...

The generation of single sideband (SSB) signals first came to my attention via ham radio back in the early 1960s. My call was then and still is WA2IBH. The best phonetic I had for that call sign was ...

In the recent decade, various schemes of field recovery with direct detection have been investigated in short-reach optical communications. Since direct detection generally provides only intensity ...

Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare reception of ...

The upper or lower sideband of a carrier frequency that is amplitude modulated. To save power, the carrier and one of the sidebands is eliminated, leaving only a single sideband for transmission.

In the old days, a shortwave radio was a major desk fixture. These days, you can get truly diminutive radios. However, most of them only have AM capability (that is, no simple way to receive ...

The author is president of Omnia Audio in Cleveland. The FM stereo transmission system employed in worldwide broadcasting has been in place since 1961. The rules governing stereophonic performance ...
