Letters to Bob I57

27. Getting some engineers to hold design reviews is hard. By law, our drafting depart-
ment will not start a PC-board design until the designer hosts a review. The drafting
supervisor can easily enforce this policy because he does not report to the first-level
engineering managers. The moral indignation of the designer's peers informs the
quality of the review.
28. Those partial but detailed schematics National Semiconductor sometimes places on
data sheets provide valuable insight into how a part may be acting in unusual circum-
stances. Please encourage National to continue the practice.

Hello to Mr. McCammon:

Well, I thank you for your comments, many of which are excellent. I will comment
on some of them individually, but, as a collection, they are the best new ideas that
anybody has given me.

* RAP SUGGESTS ADDING DASHED CIRCUITS

Figure 13. I. This 20-db high-impedance amplifier works at audio frequencies and is a handy
troubleshooting aid. I suggest adding the dashed circuits as useful options.
