In this learning activity you'll review the hexadecimal numbering system.
Op Amp Fundamentals: The Inverting Amplifier
By Patrick Hoppe
The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Voltage and Current Amplitudes in a Series RLC Circuit
By Terry Bartelt
Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.
Op Amp Fundamentals: The Summing Amplifier
Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.
Adding Fractions With Unlike Denominators
By Tina Dietzman
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Total Impedance of a Parallel Circuit Using Complex Numbers
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
Total Impedance of a Series Circuit Using Complex Numbers: Practice Problems
Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
