Rolf Engberdingcomparison does not require gates and counting lines, resolution improvement is easy, and equipment structure is simpler. The improved technique of high linearity reflects the progress of the principle at the basic level—the linear phase comparison method with a proportional relationship of frequenc

Rolf Engberdingrs. Quite generally, such methods can be classified in three main categories; finite differences, finite elements and boundary elements. The former is probably the first successfully applied numerical method and is usually derived by direct application of a difference operator corresponding to the g
