Digital Circuit Fundamentals 2 Unit 6 – Parity Generator/Checker
Exercise 1 – Odd and Even Parity
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to generate and check the parity of 8-
bit data. You will verify your results with a parity generator/checker.
DISCUSSION
- A parity generator provides an output signal that assigns an odd or even tag to a data word.
- A parity checker determines if a data word has even or odd parity.
- The parity IC has nine input lines and two active high output lines.
- The MSB input controls the level at input I of the parity IC, simulating a ninth, or parity bit.
- DATA controls the input to the shift register.
- The summation determines whether the data word has even or odd parity.
