1. Let {X[k]}K=o be the N = 8-point DFT of the real-valued sequence x[n] = [1, 2, 3, 4]. (a) Let Y[k] = X[k]ejak + X[<k – 4 >8] be the N = 8-point DFT of a sequence y[n]. Compute y[n]. Note: Do NOT compute X[k]. (b) Let Y[k] = X*[k] be the DFT of the sequence y[n], where * denotes the conjugate. Compute the sequence y[n]. Note: Do NOT compute X[k].
Q1 Zero Kelvin 1 Point What is the significance of the temperature O K in the Kelvin scale? O O K is the temperature where water would freeze in outer space O OK is the temperature at which ice crystals form OOK is the temperature where all motion of the particles in a substance would stop O O K is the temperature of the surface of the Sun Save Answer
