What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
Circuit for single tuned amplifier?
A single tuned amplifier basically consists of a tuned circuit (which may consist of an IFT or a parallel tuned LC circuit) connected to the collector of an amplifier circuit (in Common Emitter configuration). The tuned circuit is designed to get a resonant frequency equal to the incoming frequency signal that arrives at the base. The Single Tuned Amplifier gives maximum amplification to that particular incoming frequency which matches the resonant frequency of the tuned circuit and attenuates all other frequencies. Thus it gives sharp selectivity with a high Q-factor.
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
What is stagger tuned amplifier?
Stagger Tuned Amplifiers are used to improve the overall frequency response of tuned Amplifiers. Stagger tuned Amplifiers are usually designed so that the overall response exhibits maximal flatness around the centre frequency.It needs a number of tuned circuit operating in union. The overall frequency response of a Stagger tuned amplifier is obtained by adding the induvidual response together. Since the resonant Frequencies of different tuned circuits are displaced or staggered, they are referred as STAGGER TUNED AMPLIFIER.The main advantage of stagger tuned amplifier is INCREASED BANDWIDTH. Its Drawback is Reduced Selectivity and critical tuning of many tank circuits. They are used in RF amplifier stage in Radio Receivers.
The main application of tuned voltage amplifier?
As a frequency receiver

What is meant by double tuned amplifier?
An amplifier with tuned filters on both input and output.

What Advantages of double tuned amplifiers over single tuned amplifiers?
The primary advantage of a double tuned amplifier, such as, an amplifier with a tuned circuit on the input and the output, is narrow bandwidth. Another advantage to the circuit is impedance matching with the previous stage, etc. And last but not least your double tuned amplifier will have more gain for electrons spent getting the job done. In our battery operated everything world that is an important design factor.

What is a scientific word for q?
Q is often used to connote "electric charge".The Q factor of tuned circuits is a measure of "quality factor". It is a measure of how well the tuned circuit selects wanted frequencies and rejects the unwanted.
The main application of tuned voltage amplifier?
As a frequency receiver
Is tuned voltage amplifier used in public address system?
no
What is single tuned voltage amplifier?
it is a circuit consisting of a tuned circuit with a capacitor in parallel with inductor and it is connected to collector terminal in common emitter configuration,, and it is used as frequency receiver
What is the bandwidth and Q factor for a good tuned amplifier?
It depends on the signal you are trying to receive. For instance, the AM frequency band lies around 500KHz to 1700kHz. Lets say you have a tuned amplifier such that the resonant frequency was set roughly in the middle of that band at 1000kHz (1MHz). AM radio stations typically space out their broadcasts 9-10kHz. So if Q=f_resonant/f_bandwidth the Q of a tuned amplifier with a bandwidth of 10kHz (which would be decent, maybe a little spill over), would be: Q=1Mhz/10kHz Q=100 The higher the Q, the greater the selectivity. Too high be a bad thing too.
