3 8 Decoder Kmap

The tool computes the 3-to-8 decoder mapping from three binary inputs to eight one-hot outputs. It takes A, B, C values and produces Y0 through Y7 such that only the output corresponding to the binary value of ABC is 1. This is useful for validating decoder portions of digital circuits, teaching one-hot encoding, and generating reference data for documentation. Conceptually, interpret ABC as a 3-bit number N = 4*A + 2*B + C (A as MSB); Yi is 1 exactly when i equals N. The tool can present a full truth table, boolean expressions for each Yi, and optionally provide minterms for Karnaugh-map mapping. Users benefit from a clear, deterministic mapping and the ability to align results with K-map based simplification. The design is suitable for educational contexts, design verification, and quick circuit analysis. Core value lies in precise, repeatable mappings, explicit minterm enumeration, and the ability to export or copy results for reports or lesson materials. The tool targets electronics learners, instructors, and engineers seeking a lightweight reference for decoder behavior and logic design workflows.
