Abstract

PURPOSE: To reduce the capacity of a storage medium without degrading resolution by storing data according to the change of the digital value of input analogue data.
CONSTITUTION: The analogue wave from a waveform generator is subjected to sample hold in 11, and is subjected to analogue-digital conversion in 13 and is held in register 14. Continuously, at the next sample time, contents of register 14 are transferred to register 15, and the new digital quantity which is inputted at this time is held in registr 14. Next, contents of registrs 14 and 15 are compared with each other; and if these values are equal to each other, counter 17 is increased by 1. This operation is repeated in order until values of registers 14 and 15 are different from each other. Then, when contents of registers of registers 14 and 15 become different from each other, contents of register 15 and counter 17 are transferred to write register 18 and are stored in recording medium 19.
