Acknowledgements 



Space does not permit listing all of the people who contributed to the 

 success of this work. However, we wish to mention S. A. Levin for his 

 work on cause shapes, R. H. Klie for his leadership in system studies, 

 E. T. Harkless for his study of cosine equalizers, and E. Ley for mechani- 

 cal design of equaUzers. Also mention should be made of C. J. Custer 

 and E. G. Morton for their work on regulator circuits, A. R. Rienstra 

 for studies of gain enhancement, C. H. Bidwell for ''chain action" 

 analysis, and F. R. Dickinson for mechanical design of regulators.
