Problem 58-4    Souirce:   Example 13.6 - page 343 - BARTKOWIAK, Robert A. - Book: Circuitos Elétricos - 2ª ed. - Editora Makron Books - 1999.

A series resonant circuit has a resonance frequency of 10 KHz. If Q = 100, what are the cut-off frequencies?

Solution of the Problem 58-4   

Note that Q = 100 is much larger than 10. Therefore, we can use the eq. 57-10 and subsequent to resolve the problem. So:

Thus, knowing the bandwidth and resonant frequency:
