Show advantages and disadvantages of a r-c couple amplifier, Electrical Engineering

Assignment Help:

Q. What are the advantages and disadvantages of a R-C coupled amplifier.

Advantages

· It has excellent frequency response. The gain is constant over the audio frequency range which is the region of most importance for speech, music etc.

· It has lower cost since it employs resistor and capacitors, which are cheap.

· The circuit is very compact as the modern resistors and capacitors are small and extremely light.

Disadvantages

· The R-C coupled amplifiers have low voltage and power gain.

· They have the tendency to become noisy with age, particularly in moist climates.

· Impedance matching is poor. It is because the output impedance of R-C coupled amplifier is several hundred ohms, whereas the input impedance of a speaker is only a few ohms. Hence, little power will be transferred to the speaker.
