2) the impulse response of a discrete-time lti system t is h[n] = c1δ[n] + c2δ[n − 1] − c2δ[n − 3] − c1δ[n − 4] where c1 and c2 are real positive constants. a) is t a causal fir generalized linear phase system of one of the four types described in class? if so, which type (i, ii, iii, or iv)? explain. b) find the magnitude response |h(ω)| of the system. simplify your answer. c) find c1 and c2 so that |h(ω)| satisfies |h( π 6 )| = 1 and |h( π 3 )| = 0.6 + 0.4 √

step-by-step explanation:

play black ops 4 answer a

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
