Q. Mention the advantages and disadvantages of direct coupled coupling?
Advantages:
1.Simple circuit due to minimum use of resistor
2.Low cost due to absence of expensive coupling device
Disadvantages:
1.It cannot be used for amplifying high frequencies
2.The opertaing point is shifted due to temperature variations.
