Abstract
A lookup table includes a complementer, a memory and a switching element. The complementer selectively complements a subset of bits of a multibit designation of an angle based on a most significant bit of the multibit designation to produce an address signal. The memory is addressed by the address signal and produces two values. The switching element receives the two values from the memory and selectively outputs the values based on the most significant bit.
