 note = {application/pdf, An A/D conversion device connected with a printer interface has been developed. This device is supposed to be used not only as an A/D converter but as a teaching material of measurement and control in the course of technical education at a technical high school and a junior high school. This device is easy to be made at a low cost; it is simply composed of a 4-bit D/A converter with a dual operational amplifier, some resistors and a comparator. It has no exclusive integrated circuit for an A/D conversion device, and its process is needed to be programmed by BASIC language. So learners can practice and understand a mechanism of A/D conversion through learning the program.},
