worksheet 8 second

10. When would you most likely couple stages of an amplifier with a tuned transformer? 11. What are the major drawbacks of transformer coupling? 12. In high frequency applications, what does an ideal amplifier do? 13. What determines the bandwidth of a tuned amplifier? 14. What is the difference between a capacitively coupled amplifier and a direct- coupled amplifier? 15. What are some advantages and disadvantages of negative feedback? 16. What is the purpose of the capacitor that is connected in parallel with Rez in the negative feedback arrangement? 17. How does the feedback voltage influence the negative feedback circuit? 18. How can the gain be controlled in the negative feedback arrangement?

Answer 1

Answer 10 - If we want to amplify a Specific range of frequency or nassow band frequency than we use the tuned circuit at the collector of the amplifier

Answer - 11 Transformer produce humming sound it gake amplifier bulky. so it can no more fabricated on IC. It produce in the poow frequency response frequency (f) Answer 12 at high frequency, The ideal amplifier start Oscillate.

The ideal amplifier is called a ideal of amp, which has all properties to amplifier frequency is so high so ito Could not stablized the gain and start osulletic Answer-13 Quality factor (0) and resonant ena y to determined the Bandwidth BLUE Av Bu al BW
dear student, i have authority to solve one question as per HomeworkLib guidelines.but i have solve 4 questions for your help. Thank you
