Learners read the characteristics of the TTL series. Examples are given and subfamilies are compared.
By Terry Bartelt
In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.
Series RL Circuit Practice Problems
By James Bourassa, John Rosz
Students calculate current, phase angle, resistor voltage, inductor voltage, and power.
Transfer Functions: The RL High Pass Filter With Bode Plot
By Patrick Hoppe
Learners read how the transfer function for a RL 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.
Pulse Train Fundamentals
Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.
