#106132 - What a messy circuit...
Responding to: Ian Bell's previous message
This quiz was given 1987. Do you really think that the use of Germanium diodes is assumed? If it shall refer to DTL, implemented on same chip, then, if a silicon transistor is used, also silicon diodes are to be expected.

The usefulness of this circuit is higly questionable and seems to be totally fabricated. And very probably the maker of this quiz thinks that this circuit will work properly. But a really good student will analyze, that this circuit is totally misdesigned and might give the 'wrong' answers.

By the way, just this question is also discussed here:

I hate those quizes, because they suffer from the stupidity of maker of quiz. One is for sure: If it's silicon diodes, the circuit will definitely not work reliably!
