Circuit forms efficient cosine calculator: 10/25/2001
EDN - Design Ideas / The circuit in Figure 1 converts a 10V
analog voltage representing an angle between MIN and MAX and
emits a voltage equal to 10 cos . This circuit can have an
accuracy of better than 1% over 120 or better than 0.2% over
90 . These figures represent an order-of-magnitude
improvement over a Taylor-series estimate for the same range
and for...
