He heard the sound of a mobile amplifier, and strained his ears toward it. I can't detect any heart action even with the amplifier. The battery would be forwarded as soon as it reached the Wireless Club and had been inspected, and the amplifier would go with it. The receiving transducers would feed from amplifiers to earphones. amplifier | American Dictionaryamplifier noun[ C ] us/ˈæm·pləˌfɑɪ·ər/ an electronic device that strengthens the electric signal used to carry sound Examples of amplifieramplifier The working-class adolescents use quite generally as a positive amplifier rather than as a hedge. 10. However, small electrohydraulic valves with a high degree of precision are much more expensive and less reliable than powerful electrical amplifiers and controllers. As a result, large apertures are required for excimer amplifiers to obtain output power high enough. The amplitude and phase profiles of the fundamental have been educed from the fluctuating signal with a lock-in amplifier, phase-locked to the excitation signal. The author claims that some amplifiers do not fit comfortably with certain adjectives and are not as interchangeable or synonymous as previously thought. The electrode tip was positioned next to the soma and penetration was achieved using the amplifier's buzz feature. In the second step, six several terawatt lasers are expected to be obtained by simultaneous amplification of the six beams of the e-beam pumped amplifiers. The output of the hot-wire amplifier vacuum thermocouple or the wave-analyser vacuum thermocouple was used as the second ordinate on the table. The remaining three beams are split into six beams and are amplified sequentially again in the main amplifier. A sinusoidal signal from a function generator was amplified in an audio amplifier before it was fed to the speaker. The output of this coil is amplified using a differential amplifier and a scaling amplifier. In this model, only the spreading loss was considered and the loss is assumed to be compensated by an auto-gain amplifier. In addition, the analysis also includes intensifiers, such as universal and negative pronouns (all, nothing), amplifiers (a lot, forever), and emphatics (extreme/-ly/, total/-ly/). However, improvisers also often participate with relatively simple analogue devices such as ring modulators, amplifiers or contact microphones attached to instruments. The regenerative amplifier included in the amplifier introduces some prepulses several nanoseconds before the main pulse. These examples are from corpora and from sources on the web.
