What is wideband amplifier?
A wideband amplifier has a precise amplification factor over a wide frequency range, and is often used to boost signals for relay in communications systems.
A narrowband amp amplifies a specific narrow range of frequencies, to the exclusion of other frequencies.
An audio amplifier amplifies audio frequencies..
Which amplifier class has highest linearity and lowest distortion?
Which of the following amplifier class have the highest linearity and lowest distortion? Explanation: Class A amplifier has the highest linearity and the lowest distortion. The amplifying element is always conducting and close to the linear portion of its transconductance curve.
What is tuned RF amplifier?
A tuned radio frequency receiver (or TRF receiver) is a type of radio receiver that is composed of one or more tuned radio frequency (RF) amplifier stages followed by a detector (demodulator) circuit to extract the audio signal and usually an audio frequency amplifier.
Which power amplifier has the highest collector efficiency?
Class C power amplifierClass C power amplifier has the highest collector efficiency.
What are the disadvantages of synchronous tuned amplifiers?
Disadvantages of Tuned amplifiersThe overall circuitry is costly as well as bulky due to the presence of inductors and capacitors in tuned circuits.Amplification in the range of audio frequency cannot be achieved.Increase in bandwidth leads to complexity in the circuit.
What is double tuned circuit?
A double-tuned amplifier is a tuned amplifier with transformer coupling between the amplifier stages in which the inductances of both the primary and secondary windings are tuned separately with a capacitor across each. … Two stages of double-tuned amplifier have 80% of the bandwidth of a single stage.
What is transistor tuned amplifier?
A simple transistor amplifier circuit consisting of a parallel tuned circuit in its collector load, makes a single tuned amplifier circuit. The values of capacitance and inductance of the tuned circuit are selected such that its resonant frequency is equal to the frequency to be amplified.
What is meant by stagger tuned amplifier?
Staggered tuning is a technique used in the design of multi-stage tuned amplifiers whereby each stage is tuned to a slightly different frequency. In comparison to synchronous tuning (where each stage is tuned identically) it produces a wider bandwidth at the expense of reduced gain.
What is electronic neutralization?
Electronic neutralization is the deliberate use of electromagnetic energy to either temporarily or permanently damage enemy devices which rely exclusively on the electromagnetic spectrum.
What are the advantages of double tuned amplifier over single tuned amplifier?
17. What are the advantages of double tuned amplifier over single tuned amplifier? 1. It provides larger 3 dB bandwidth than the single tuned amplifier and hence provides the larger gain-bandwidth product.
What is the function of tuned amplifier?
A tuned amplifier has a frequency response similar to that of a band-pass filter except with gain. In communications, tuned amplifiers are commonly used to separate a desired frequency from a composite waveform.
What are the requirements of tuned amplifier?
selected band of frequencies. 3.1. 4 Requirements of Tuned Amplifier The basic requirements of tuned amplifiers are : • The amplifier should provide selectivity of resonant frequency over a very narrow band. The signal should be amplified equally well at all frequencies in the selected narrow band.
