Circuit forms efficient cosine calculator: 10/25/2001 EDN - Design Ideas / (Electronic circuit added 10/03) 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... .
