Question

Difference between single tuned and double tuned amplifier

Answer 1

a single tuned amplifier consist of parallel tuned circuit in its collectors load makes single tuned amplifier.

I HOPE IT WILL HELP YOU.

Answer 2

Answer:

to answer the above question you must first understand that:

What is a Tuned Amplifier?

Tuned amplifiers are the amplifiers that are employed for the purpose of tuning. Tuning means selecting among a set of frequencies available, if there occurs a need to select a particular frequency while rejecting all other frequencies, such a process is called Selection.

These tuned amplifiers are used in high or radio frequency applications such as in TV and radio circuits.

How does a tuned amplifier function?

The circuits of video signal amplification in the wideband range use these amplifiers for wireless long-distance communications, these amplifiers due to high gains are used at the receiving stage, these are used as radio frequency amplifiers.

There are two basic types of tuned amplifiers:

• Single tuned amplifiers
• Double tuned amplifiers

1. Single tuned amplifier: Single tuned amplifiers use one parallel resonant circuit as the load impedance in each stage and all the tuned circuits are tuned to the same frequency.

2. Double tuned amplifier: Double tuned amplifiers use two inductively coupled tuned circuits per stage, both the tuned circuits being tuned to the same frequency.

The advantages of the Double Tuned Amplifier is:

1. it has a narrow bandwidth.
2. One more advantage of this circuit is impedance matching using the previous phase.
3. It gives a frequency response including flatter sides.
