Digital Counter Display Manual
The manual introduces a digital counter project that uses a 7490 decade counter, a 7447 BCD‑to‑7‑segment decoder, and a 7400 NAND gate array. It explains the purpose of the experiment, the required components, and basic theory behind the circuits.
Step‑by‑step procedures guide the user through wiring the circuit, verifying the counting sequence, and extending the design to a simple digital‑to‑analog converter using resistor networks. The document also includes troubleshooting questions and expected output values. This manual is written in Japanese.
