1. A coefficient determinator system comprising: a first memory lookup table storing a number of sine/cosine pairs; a sine function operative to receive an input value and to compute a sine of the input value utilizing a retrieved sine/cosine pair of the number of sine/cosine pairs from the first memory lookup table; a second memory lookup table storing a number of reference values; an inverse function operative to receive the input value and to compute an inverse of the input value utilizing a retrieved reference value of the number of reference values from the second memory lookup table; and a multiplier operative to multiply the sine of the input value with the inverse of the input value to provide a sinc of the input value.
