Now we can do something similar with the two 2-point DFT's to get equations for a; for j = 0,1,2,3: (DFT (αo, α2)o + DFT (αo, α2)1) (DFT (ao, a₂)o-DFT (αo, α₂)1) (DFT (α₁, α3)0 + DFT (α₁, α3)1) -(DFT (a1, a2)3 — DFT (α₁, α3)1). Exercise 1. Using the definition of DFT in Equation (3), prove Equations (11). αo 4₂= a₁ =
