In this learning activity you'll explore the operation of frequency division using several different types of counters.
In this learning activity you'll examine the terms associated with a grouped frequency distribution and follows the steps to construct a grouped frequency distribution using manual methods.
Students read the vocabulary associated with frequency response as it relates to an amplifier.
Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.
Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.
Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.
Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
Students examine an Excel spreadsheet to determine range, class, and width.
Learners follow steps to establish the lower and upper limits in a spreadsheet.
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
Learners follow steps to establish class boundaries and tally the data using a spreadsheet.
Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Learners read a description of the DC offset function, the 50 ohm and 600 ohm output terminals, and the TTL/CMOS output terminal.
Students follow steps to transfer data from a list to a histogram.
