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 ...

How photonics can provide high-performance RF filtering. The photonics topology used to implement the principles. Results of various performance tests. It may seem at first glance that the electronic ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

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 ...
