SINE_COSINE

Published:2009/7/6 3:58:00 Author:May | From:SeekIC

Uses National SK0003 sine/cosine look-up table kit consisting of four MOS ROMs and three output adders. Combination implements equation sin θ=sin M cos L + cos M sin L.Worst-case error is 1 5/8 bits in least significant bit. Cosine is approximated with loss in resolution of1/2 bit in 11-bit input or1/4 bit in 10-bit input.- Memory Databook, National Semiconductor, Santa Clara, CA, 1977, p 6-98-6-99.
