Unformatted text preview: new = Â£ f X x Â¤ Â· f X âˆ— x âˆ— Â¸ = f 2 XX âˆ— + xx âˆ— . The matrix XX âˆ— has 4 m 2 entries, so multiplying it by f 2 requires O ( m 2 ) multiplications. The number of multiplications needed to form xx âˆ— is also O ( m 2 ) multiplications. CHALLENGE 8.5. The results are shown in Figure 8.2. The average error in the angle estimate is 0 . 62 degrees, and the average relative error is 0 . 046. The results are quite similar to those for rectangular windowing....
