Applications Amplifiers Have Many Useful Applications In Electronics.

Amplifiers have many useful applications in electronics. Similarly, transistors can be used for more than just amplification. What are some of the types of amplifiers and what are their classifications?     In your own words compare the applications of different amplifier types and classes. Explain what is meant by 'TFT' that you always find in the specs for laptop displays. Discuss an application of Darlington Pair transistors.
