DMT 124/3DIGITAL FUNDAMENTAL 1 WEEK #3 LOGIC GATES
Logic Gates • Inverter (NOT Gate) • AND Gate • OR Gate • NAND Gate • NOR Gate • Exclusive-OR (XOR) & Exclusive-NOR (XNOR) Gates • Fixed-function logic • IC Gates
Introduction Three basic logic gates • NOT Gate • expressed by “ ‘ ” or “ ¯ ” • AND Gate • expressed by “ . ” • OR Gates • expressed by “ + ” sign (not an ordinary addition)
NOT Gate (Inverter) a) Gate Symbol & Boolean Equation b) Truth Table (Jadual Kebenaran) c) Timing Diagram (Rajah Pemasaan)
AND Gate a) Gate Symbol & Boolean Equation b) Truth Table (Jadual Kebenaran) c) Timing Diagram (Rajah Pemasaan)
AND Gate - Application Seat Belt Alarm System
OR Gate a) Gate Symbol & Boolean Equation b) Truth Table (Jadual Kebenaran) c) Timing Diagram (Rajah Pemasaan)
