Which part of a filter\'s frequency response indicates how much a signal will be

Question

Which part of a filter's frequency response indicates how much a signal will be attenuated or amplified by the filter? a. None of the other responses b Real part c. Phase d. Magnitude e. Imaginary part QUES TION 2 Which of the following is the correct defintion for group delay? a The negative of the derivative of the phase b. The negative of the phase O c. None of the other responses d The negative of the integral of the phase o e The integral of the phase f. The derivative of the phase g. The phase

Explanation / Answer

A-1 Option d magnitude

Explanation: magnitude =output/input

So if magnitude is less than 1 its output will be attenuated otherwise it will be amplified for value greater than one.

A-2: Option A Group delay is negative derivative of the phase.
