From a textbook:
"The parity bit is chosen so that the total number of 1's in a coded frame is even. We say that the coded frame has even parity."
From a basic explanation in a Web site:
"Computing parity involves counting the number of ones in a unit of data, and adding either a zero or a one (called a parity bit) to make the count even (for even parity) or odd (for odd parity).
For example, 1001 is a 4-bit data unit containing two one bits; since that is an even number, a zero would be added to maintain even parity,...."
To my surprise, from AN 160 from Linx Technologies:
"A parity check is accomplished by adding all of the '1's in a string of bits. For even parity, if the number is even, then the parity bit is set, otherwise it is not."

Comments anyone?
