Twelve pages of notes based on the function of combinational logic circuits. Examples of combinational circuits are given and explanations of how to write truthtables and express logic functions using Boolean Algebra. The notes show the effect of combining a variety of logic gates and how logic gates. Combining two NOT gates to make a buffer Combining AND, OR and XOR gates with a NOT gate Writing truthables Multiple input AND and NAND gates Multiple input OR and NOR gates Multiple AND gate circuits Multiple OR gate circuits Combining AND, OR and NOT gates A note on algebra Inverting inputs The magical NAND gate - Combining NAND gates to form other gates The magical NOR gate - Combining NOR gates to form other gates Note: PART 1 is available to download as an introduction to logic gates.

A workbook to introduce students to aspects of health & safety in the workshop and work environment. It includes: Declaration front sheet Identifying chemical safety signs Identifying hazard signs Identifying mandatory signs Identifying prohibition signs Identifying safe condition / advisory signs Identifying PPE and their use Identifying workshop tools (x3) Identifying hazards - two very simple risk assessments

Seven pages of notes relating to logic gates. Building from the basics of the difference between analogue and digital signals and how logic levels can be represented by voltages. Circuit symbols, boolean expressions and truth tables are explored. This resource is an introduction to PART 2 which covers concepts of combinational logic. Logic and voltage levels Logic gates Logic gate symbols AND, OR and XOR gates NAND, NOR and XNOR gates NOT gates Propagation delay
