Computer-Aided Network Tuning

An important part of preproduction design evaluation of networks requiring tuning at the test site is to demonstrate that they can be tuned to specifications by manual methods. A computeroriented tuning strategy is described that uses response sensitivity to component variations to select a best component at each stage as well as its direction of movement and size of adjustment. This method is superior to pattern-search techniques and sequential linear-search procedures. Computation time is considerably reduced by the use of sensitivity data to predict network responses.
