Instructions: 1) Solve all the questions it) Indicate the compiler used
Exercice 1
1- Define : Astable, Monostable, Multivibrator, Latch, Flip-Flop
2- Compare combinatory logic circuit and sequential logic circuit
3- Compare a latch and a flip-flop
4- Name 03 latches, draw the corresponding circuit diagram for each of them as well as
the truth table
5- Name 02 flip-flops, draw the corresponding circuit diagrams as well as the truth table
Exercice2
Consider the diagram below
1. Draw the waveforms
of
the outputs 01, Q2 and 03.
2. Express the frequency fi,
f2
and
f3
of the waveforms of the outputs 01, Q2 and
03 respectively, in function of the frequency lc, of the clock signal.
3. Using the principle of the circuit above, design a digital system capable
of
dividing the frequency of the clock signal by 32.
