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.
The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. If a particle of air undergoes 1000 longitudinal vibrations in 2 seconds, then the frequency of the wave would be 500 vibrations per second. high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. Amazingly, many people, especially those who have been musically trained, are capable of detecting a difference in frequency between two separate sounds that is as little as 2 Hz.
