disparity
In pulse-code modulation (PCM), the digital sum, i.e., the algebraic sum, of a set of signal elements. Note: The disparity will be zero and there will be no cumulative or drifting polarization if there are as many positive elements (those that represent 1) as there are negative elements (those that represent 0).
