Comparators (1-bit & 4-bit)

To study and implement Digital Comparators (1-bit and 4-bit).

Theory & Concepts

Click to collapse detailed explanation

1. Digital Comparators

A comparator is a combinational circuit that compares two numbers (A and B) and determines their relative magnitudes (A > B, A = B, or A < B).

2. 1-Bit vs 4-Bit

A 1-bit comparator compares two single bits, while a 4-bit comparator (like the 74L85 IC) compares two 4-bit nibbles.

Procedure

  1. Input two 4-bit numbers A and B.
  2. Observe which output (GT, EQ, LT) turns high.
  3. Test with values where A > B, A = B, and A < B.
