Comparison of Different Types of Coupled Amplifiers

Here in the table we are describing the differences between RC coupled, Transformer Coupled, and Direct Coupled Amplifier –

Parameter	RC Coupled	Transformer Coupled	Direct Coupled
1. Frequency Response	Excellent	Poor	Best
2. Cost	Less	More	Least
3. Space and Weight	Less	More	Least
4. Impedance Matching	Not good	Excellent	Good
5. Use	Voltage amplification	Power amplification	In low frequency amplifications
