Reduction of data width in transmitted multi-bit data words in an automotive system is accomplished by truncating the data at its least significant bits and accumulating the truncated bits until, over successive truncated digital words, the sum of the accumulated bits exceeds a threshold equal to the least significant bit of the truncated word. At this time, the truncated word is incremented by one least significant bit and the accumulated value of truncated bits is decremented by an equal amount. In this way, the error does not accumulate in applications which integrate the resulting truncated words.
