CHAPTER 14. ELECTRONICS 14.6
- Draw the symbols for the five logic gates, and write down their truth
tables.
- Draw a circuit diagram with an AND gate. Each input should be
connected to the output of a separate NOT gate. By writing truth
tables show that this whole circuit behaves as aNOR gate.
- Convert the denarynumber 99 into binary.
- Convert the binarynumber 11100111 intodenary.
- Explain how threeT flip flops can be connected together to makea
modulo 8 counter. What is the highest number it can count up to?
- Draw the circuit diagram for an RS flip flop(bistable) using two NOR
gates.
- Show how the circuit you have just drawn can have a stable outputof
0 or 1 when both inputsare 0.
- Operational (and other) amplifiers, logic gates, and flip flops all con-
tain transistors, and would not work without them. Write a short
newspaper article for anintelligent reader who knows nothing about
electronics. Explain howimportant transistors arein modern society.
