DISCUSSION:
1- A 7485 four-bit magnitude comparator has P=1011 and Q= 1001.
a- Determine the outputs.
b- Show how to connect the < , = and > inputs if this is to be the least significant state.
2- Draw the logic diagram for the comparison of two 4-bit binary numbers P3 P2 P1 P0 and Q3 Q2 Q1 Q0 ?
3- Draw circuit for equality comparison of two 4-bit numbers.
4- Design a digital comparator which compare two each with 2-bit using truth table method ?
5- Use 3-bit integrated comparators to compare the magnitude of two 6-bit binary numbers . Show the comparators with proper connections ?
6- Use 7485 comparators to compare the magnitudes of two 8-bit binary numbers. Show the comparators with proper interconnections.
