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.
According to our definition, this is proper sampling. The sine wave shown in (b) has a frequency of 0.09 of the sampling rate. This might represent, for example, a 90 cycle/second sine wave being sampled at 1000 samples/second. Expressed in another way, there are 11.1 samples taken over each complete cycle of the sinusoid.
