Power Law: The Relationship of Voltage, Current, and Watts
Learners examine three formulas than can be used to find dc power. Examples are given.
Transfer Functions: The RC Low Pass Filter
Students read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
The MOD 10 Counter
The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.
Transfer Functions: The RC High Pass Filter
Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
