Winter 2007
1. Do the following problems from CHR:
a. (15) 8.F
b. (15p) 8.N
2. (15p) Consider the following circuit:
It is possible that exactly one of the internal wires of this circuit (wire a, b, c or d) is permanently stuck
at1 or stuckat0. What is the minimum number of input patterns you need to apply to convince yourself
that the circuit functions correctly. List these patterns.
3. (5p) Prove that if A,B,C are sets for which both the conditions AB=AC and A+B=A+C hold, then it
follows that B=C.
4. (5p) Prove, that if A and B are sets satisfying the relation
, then A+BC=B(A+C). Do not use
Venn diagrams in conducting the proof.
5. (5p) Show that the following conditions are inconsistent:
, A=B, A’+B’=1. A, B are sets. 1 represents the universal set.
