Other Electronic Hybrids
In the early days of telephones, separate modules containing transformers and resistors were called hybrids or hybrid coils; they have been replaced by semiconductor integrated circuits.
In the early days of transistors the term hybrid circuit was used to describe circuits with both transistors and vacuum tubes; e.g., an audio amplifier with transistors used for voltage amplification followed by a vacuum tube power output stage, as suitable power transistors were not available. This usage, and the devices, are obsolete, however amplifiers that use a tube preamplifier stage coupled with a solid state output stage are still in production, and are called hybrid amplifiers in reference to this.

Famous quotes containing the word electronic:
“The war was won on both sides: by the Vietnamese on the ground, by the Americans in the electronic mental space. And if the one side won an ideological and political victory, the other made Apocalypse Now and that has gone right around the world.”
—Jean Baudrillard (b. 1929)
