Optical Ethernet overview What if all corporations could connect buildings thousands of miles apart as easily as if they were just connecting two floors of the same building? What if every access and metro network was as simple, fast, and reliable as a Local Area Network (LAN)? What if Metro Area Networks (MANs) and Wide Area Networks (WANs), with their
The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation. Frequency is the number of occurrences of a repeating event per unit time. According to Wikipedia, The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation.
1. The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency. Similarly, the peaky sinusoid in Fig. 2 has the mathematical equation, y=sin (x) -0.25 sin (3x).his waveform has the same composition as the first waveform, except the third harmonic component is out of phase with the fundamental frequency, as indicated by the negative sign preceding the â0.25 sin (3x)â term. This subtle mathematical difference produces a very different appearance in the waveform.
