In other words, the frequencies between the harmonicsĬan be thought of as having a value of zero, or simply not existing. Harmonics, or (2) the frequency spectrum is discrete, and only defined at the Means that the frequency spectrum can be viewed in two ways: (1) theįrequency spectrum is continuous, but zero at all frequencies except the The time domain repeats itself, is also called the fundamental frequency. The first harmonic, i.e., the frequency that Instance, if the time domain repeats at 1000 hertz, the frequency spectrum willĬontain a first harmonic at 1000 hertz, a second harmonic at 2000 hertz, a third That periodic signals have a frequency spectrum consisting of harmonics. That repeat themselves from negative to positive infinity. Figure 13-10 shows several examples of continuous waveforms
