A device which takes in a weak electric signal and sends out a stronger one Amplifiers are used to boost electrical signals in many electronic devices, including radios, televisions, and telephones Both vacuum tubes and transistors can be amplifiers, though today vacuum tubes are rarely used for this purpose
An electronic device used in sound system applications to convert a low level signal such as from a microphone or CD player into a high-power signal (rated in watts) capable of powering a loudspeaker to a high sound level
An electronic component used to increase the strength of a transmitted analog signal Performance is measured in deciBels (dB) Similar to a repeater in digital systems
Most commonly an electronic circuit or other device that increases the signal level by increasing voltage or current Buffer amplifiers isolate one part of a circuit from another Impedance matching amplifiers actually could decrease level Preamplifiers are designed to handle small voltages, such as microphone signals Power amplifiers are designed to drive loudspeakers
An electronic circuit that draws power from a supply voltage, or voltage source, to produce, at its output, an increased reproduction of the signal existing at its input The amplifying component could be a transistor, vacuum tube, or an appropriate magnetic device
a component or device intended to sense a signal and produce a larger version of that signal In general, any amplifying device is limited by available power, frequency response, and device maximums for voltage, current, and power dissipation Also see: voltage divider Transistors are analog amplifiers which are basically linear over a reasonable range and so require DC power In contrast, Relays are classically mechanical devices with direct metal-to-metal moving connections, and so can handle generally higher power and AC current
An electronic device used to increase the amplitude or power level of a signal Amplifiers are used in telecommunications on analog transmission lines to offset the signal loss that occurs as the signal is propagated along the line
electronic devices, spaced at intervals throughout a cable television system, used to boost the strength of the cable signal as it passes from the head end to the subscriber In coaxial cable systems, amplifiers are needed approximately every 1,500 feet Amplifiers are also used in twisted copper pair telephone lines
A device which enables an input signal to control power from a source independent of the signal and thus be capable of delivering an output which bears some relationship to, and is generally greater than, the input signal
A device used to make an audio signal greater It does not do anything more or less, although a mixer may be in the same box and the box is then called the amplifier
A device that increases signal strength In audio, two different kinds of amplifiers exist preamplifiers and power amplifiers A preamplifier provides voltage gain for the small output voltage of a source component [tuner, CD player, DVD player, tape deck or turntable], while a power amplifier amplifies the preamp signal and adds the necessary current to drive and control a loudspeaker Solid state power amplifiers are current devices while tube amps are voltage devices Depending on how much input voltage an amplifier requires to be driven to full output [a function of its input sensitivity], a preamp may never actually amplify the source signal but merely reduce it [attenuate] and add volume control and source switching A typical music amplifier sports two channels, while a single-channel amplifier is called a monoblock Home theater amplifiers feature multiple channels anywhere from 1 to 7
A device that strengthens the signal of an analog transmission As an analog signal moves further from its point of origin, it weakens in strength, so amplification is required to restore the signal quality for the receiver
a device that increases the amplitude, power or current of a signal The resulting signal is a reproduction of the input signal as well as this increase
The amplifier multiplies an electrical signal with a certain amplification factor to allow low-level measured signals to be further processed by the electronics
A device for increasing the power associated with a phenomenon without appreciably altering its quality and in which an input signal controls power from a source independent of the signal and delivers an output that bears some relationship to, and is generally greater than, the input signal
An amplifier is an electrical component that boosts the strength or amplitude of a transmitted, usually analog, signal It is functionally equivalent to a repeater in digital transmissions
An amplifier is an electronic device in a radio or stereo system which causes sounds or signals to get louder. Device that responds to a small input signal (voltage, current, or power) and delivers a larger output signal with the same waveform features. Amplifiers are used in radio and television receivers, high-fidelity audio equipment, and computers. Amplification can be provided by electromechanical devices (e.g., transformers and generators) and vacuum tubes, but most electronic systems now employ solid-state microcircuits. One amplifier is usually insufficient, so its output is fed into a second, whose output is fed to a third, and so on, until the output level is satisfactory
