Parity Bit Calculator

Find the parity bit for a byte.

Calculated Output

Parity bit 0

Number of 1 bits 4

Formula: Even: bit makes total 1s even; Odd: makes them odd

Step-by-Step Breakdown

1. Values used:

2. Value (0-255) = 156

4. Parity bit = 0

5. Number of 1 bits = 4

The math behind it

Count the 1 bits. For even parity, add a 1 if the count is odd; for odd parity, the reverse.

156 has four 1 bits, so even parity is 0.

What can parity detect?

Any single-bit error (an odd number of flipped bits).
