AmplifierAn amplifier is an electronic device or circuit which is used to increase the magnitude of the signal applied to its input.
Слайды и текст этой презентации
Слайд 3Amplifiers produces and increased version of its input signal.However, not all
amplifier circuits are the same as they are classified according
to their circuit configurations and modes of operation.
Слайд 4Types of Power Amplifiers
There are three categories of amplifiers depending
on the property of their output:
Voltage Amplifier
Current Amplifier
Power Amplifier.
Слайд 5Voltage Amplifier
These amplifiers increase the amplitude of the output voltage
of the signal.A voltage amplifier in simplest form is any
circuit that puts out a higher voltage than the input voltage.
Слайд 6Current amplifier
A current amplifier is an electronic circuit which amplifies the input current by
a fixed factor and feeds it to the succeeding circuit.
A current amplifier amplifies the current without fiddling with the voltage levels. Two transistors are used in this circuit.
Слайд 7Power amplifier
A power amplifier produces maximum power to drive a
load, It plays a pivotal role of in the whole sound
system.
Слайд 8Amplifies
Amplifies can be further classified based on the signal they
amplify:
Audio Frequency Amplifiers
Ultrasonic Amplifiers
Wide band Amplifiers
Video Amplifiers
Operational Amplifiers
Слайд 9Audio Frequency Amplifiers
Audio voltage amplifiers is an electronic amplifier that amplifies low-power electronic audio signals such
as the signal.
Слайд 10
Ultrasonic Amplifiers
They are used for specific purposes such as ultrasonic cleaning,
ultrasound scanning, remote control systems.
Слайд 11
Wide band Amplifiers
These amplifiers are used in measuring equipment such as oscilloscopes.
Слайд 12
Video Amplifiers
Video signals carry all the picture information on TV sets,
video and radar systems.
Слайд 13
Operational Amplifiers
Operational Amplifiers are linear devices that are ideal for DC amplification
and are used often in signal conditioning, filtering or other
mathematical operations (add, subtract, integration and differentiation).
Слайд 14Classes
The class gives a broad indication of an amplifer's characteristics
and performance. No amplifier is perfect in every respect or perfectly
suited for every application; there are many different applications for amplifiers and many different types available.
Слайд 15Class A
Class A amplifiers generally provide the best output quality
(the best linearity), but tend to be large, hot, heavy,
power-hungry, and inefficient.
Слайд 16Class B
Class B offer poorer linearity but are cheaper, run
cooler, and are much more efficient.
Слайд 17Class AB
Class AB are a compromise solution, aiming for the
output quality of class A and the efficiency of class
B.
