Question 1 of 27070

What type of wave is made up of sine waves of the fundamental frequency and all the odd harmonics?

🔍 Key Concepts

• Fourier series representation of periodic waves • How complex waveforms (like square, sawtooth, triangle) are built from harmonics of a fundamental frequency • Difference between using all harmonics vs. only odd harmonics in a waveform

💭 Think About

• Which of the listed waveforms is commonly described in electronics and signal theory as being composed only of odd harmonics of a fundamental? • Think about which basic waveform looks very different from a smooth sine wave, but is still representable as a sum of many sine waves. • In basic signal analysis, which standard waveform is often introduced as the classic example of a Fourier series made of odd harmonics with decreasing amplitude?

✅ Before You Answer

• Confirm which waveform (among the options) is typically built from only odd harmonics (1st, 3rd, 5th, etc.), not even harmonics. • Recall that a pure sine wave at one frequency does not contain harmonics by itself—it's just the fundamental. • Eliminate any choices that are not standard names of periodic waveforms commonly used in Fourier series examples.
