leprosy
Science; General science
A chronic infectious disease caused by Mycobacterium leprae that primarily affects the skin and peripheral nerves and, to a lesser extent, involves the eyes and mucous ...
bridge circuit
Science; General science
A circuit composed of a source and four impedances that is used in the measurement of a wide range of physical quantities. The bridge circuit is useful in measuring impedances ...
phase inverter
Science; General science
A circuit having the primary function of changing the phase of a signal by 180°. The phase inverter is most commonly employed as the input stage for a push-pull amplifier. ...
feedback circuit
Science; General science
A circuit that returns a portion of the output signal of an electronic circuit or control system to the input of the circuit or system. When the signal returned (the feedback ...
emitter follower
Science; General science
A circuit that uses a common-collector transistor amplifier stage with unity voltage gain, large input resistance R i , and small output resistance R o (see illus. ). In its ...
voltage-multiplier circuit
Science; General science
A circuit which produces a dc output voltage that is a fixed multiple of the input dc voltage or the peak voltage of an ac input waveform. This fixed multiple is approximately an ...
plasmid
Science; General science
A circular extrachromosomal genetic element that is ubiquitous in prokaryotes and has also been identified in a number of eukaryotes. In general, bacterial plasmids can be ...
