Consider the following 256-point DFT X[k]=648[k – 21] +168[k – 55] +328[k -95]+328[k – 161] +160[k – 201]+648[k – 235] for 0 <k 255. Determine the 256-point inverse DFT (IDFT) x[n] of X[k]. (Note: x[n] can be expressed as a real-valued signal/sequence.)
B3 a. Solve for x in this equation: 2x + 11 = 2 (mod 4). b. What are the sets of units and zero divisors in the ring of integers modulo 22? (Specify at least the smaller set using set-roster notation.) c. Find a formula for the quotient and the exact remainder when 534 is divided by 8. Hint: find the remainder first by modular arithmetic. Then subtract the remainder from the power and divide to find the quotient.
