Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.
Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates
In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.
Students view schematics and truth tables that demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NAND gates.
