This technology was a predecessor of digital signal processing (see below), and is still used in advanced processing of gigahertz signals.
At dozens of gigahertz, the radiation is absorbed in the top fraction to top few millimeters of skin.
This effect is most widely used in microwave ovens which operate at gigahertz frequencies.
Frequencies up to several gigahertz are used in acoustic microscopes.
The rate is also variable, capable of ranging from kilohertz to gigahertz.
This has allowed synchronous microprocessors to have clock rates ranging from tens of megahertz to several gigahertz.
It scanned through the microwave spectrum from 1.400 to 1.720 gigahertz in eight hops, with two seconds of observation per hop.
Wire wrap was used for assembly of high frequency prototypes and small production runs, including gigahertz microwave circuits and super computers.
