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.
In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.
Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.
In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.
In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.
Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
