Consider the LTI system with frequency response: Hd(ω) = 1 + sin(2ω) − j cos(2ω) (2) Determine the response y[n] when: (a) x[n] = 3 + 2 sin( π 4 n) + 4e −j π 2 n . (b) x[n] = 1, ∀n. (c) the input is a 2-sample delayed version of x[n] in part (a)

im not sure

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
