C. Three
D. Four
Answer:A
How many quantization errors are present in one complex valued multiplication?
A. One B. Two C. Three D. Four
Explanation: We assume that the real and imaginary components of {x(n)} and {WNkn} are represented by ‘b’ bits. Consequently, the computation of product x(n). WNkn requires four real multiplications. Each real multiplication is rounded from 2b bits to b bits and hence there are four quantization errors for each complex valued multiplication.
