My black “bible”: Bedraggled, beat-up but brilliant MYJ-50 years of wisdom

I received my original copy in 1964, and I set my self to the task of essentially memorizing the contents, but the small matter of military service intervened. About 3 years later, I was able to obtain some of the Ft. Monmouth sponsored and reported material that had been assembled as the backbone of this great book, and returned to my studies of this “Book of Knowledge”. I cannot say that the entire book has been set to memory, because I still uncover gems from time to time. In this paper, I will discuss one such “gem”, maintaining absolute bandwidth in a tunable filter.
