There are lots of reasons to learn digital logic which is the foundation for digital computers and IED’s (Intelligent Electrical Devices). Various numbering systems will be looked at along with binary numbers as they lead into Binary Arithmetic. From there Logic Gates & Switches will form the basis of further study with Combinational Logic Functions. Electromechanical Relays are first used to demonstrate logical functions as they will then lead to more complex circuitry of Sequential Circuits, Shift Registers and solid state components. Who this course is for: Those involved with relaying and metering equipment; engineers, technologists, technicians, electricians, students
