Question

A security system implementation company is contacted by DLD lab, for the implementation of authentication system so that BEE-2 students can get lab access. The system will utilize RFID based university card scanner, password entry and verification mechanism and a fingerprint scanner. The system should work as follows: the student should get its RFID card scanned by the system. If scanning is done successful (valid) then the system will ask you to provide password. Along successful scanning and a valid password, the access is granted. If in any case the above verification is avoided, then the student is required to pass through fingerprint scanning. Only on matched fingerprint, the student is granted access. LA=F (FP, PW, RFID) Where FP: fingerprint PW: password entry RFID: RFID scanner LA: lab access a) Compute the truth table for the system b) Using part(a) write the system Boolean function c) Simplify the system to minimum number of gates using K-map d) Design the system obtained in part (c ) using NAND gate only
