D. a flip-flop
E. a fanout

(GR8677 #38)

Solution:

Diode:




The above logic circuit represents an OR gate where the inputs are connected to the anodes of diodes and the cathodes to the output.

For an AND gate, the diodes are reserved. The cathodes are connected to the inputs and anodes to the output.
