Abstract
In a parallel digital signal delivered from an AD converter, '1' appearing in a bit position nearest to the most significant digit (MSD) is detected, and the parallel digital signal is converted into a serial digital signal consisting of a weight character indicating this specific bit position and a data character indicating the numerical value of the data. Further, a weight bit is provided for changing the weight of the output of the AD converter depending on the analog quantity subjected to AD conversion so as to reduce the number of bits required for coding the parallel signal.
