This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.
Bandwidth Capacity Techniques
By Dennis Fontaine, Terry Bartelt
In this learning activity you'll follow the process of converting digital data into a series of analog signals.
Transistor Fundamentals: Decibel Gain, Power, and Voltage
By Patrick Hoppe
Students read about decibel power gain and decibel voltage gain. Examples are given for each.
The Basic Operation of a Diode
By Terry Bartelt
In this interactive and animated object, learners examine the operation of a semiconductor diode when it is forward and reverse biased. A brief quiz completes the activity.
DC/AC I: Unit 11 Sample Exam
Learners answer six questions about transformers.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
By Glenn Sokolowski
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
The Zener Diode: Practice Problems
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
You'll learn to identify frequency bands of the electromagnetic spectrum licensed by the FCC.
Radio Frequency Modulation
You'll learn some concepts related to radio frequency modulation.
