1. The problem statement, all variables and given/known data transfer function: H(s) = 1/(s^2+s+1). question: compute half-power frequency 2. Relevant equations none 3. The attempt at a solution I got 4 answers: -0.605i, 0.065i, -1.169, 1.169 I know that only two of these are correct, one is 1.169 instead of -1.169 because frequency cannot be negative. Then I wrote the two imaginary answers into phaser form. I got 0.065<-90degree and 0.065<90 degree. Could someone tell me which phase I should choose and why?
