Expert Solution
Step 1: Summarize the given information.

The frequency response function of a second-order filter is given as

H open parentheses j omega close parentheses equals H subscript 0 fraction numerator bevelled fraction numerator j omega over denominator omega subscript L end fraction over denominator open parentheses 1 plus bevelled fraction numerator j omega over denominator omega subscript L end fraction close parentheses open parentheses 1 plus bevelled fraction numerator j omega over denominator omega subscript H end fraction close parentheses end fraction space space space... open parentheses 1 close parentheses.


To

  • write  the frequency response function in the following standard form H open parentheses j omega close parentheses equals H subscript 0 B P end subscript H subscript B P end subscript and
  • prove that the quality-factor of the wideband bandpass filter is always 1 half irrespective of values of omega subscript L and omega subscript H.
