W : Build on studentsâ knowledge of literary elements by explaining how to draw conclusions, including determining the theme, based on information in folklore. H : Engage students by using the story Goldilocks and the Three Bears to model how to draw conclusions based on text.
For a signal whose fundamental frequency is f, the second harmonic has a frequency 2 f, the third harmonic has a frequency of 3 f, and so on. Let w represent the wavelength of the signal or wave in a specified medium. The second harmonic has a wavelength of w /2, the third harmonic has a wavelength of w /3, and so on.
For this example, the fundamentals are spaced 25 kHzapart, thus, a third-order distortion product appears 25 kHz above the two originalfrequencies f 1 and f 2 and the other appears 25 kHz below the two original frequencies.The second harmonic of f 2 mixes with the fundamental f 1.
