PPT-Orthogonal Frequency Division Multiplexing

Basics Frequency of Signals Sinusoidal signals have a distinct unique frequency An arbitrary signal does not have a unique frequency but can be decomposed into many sinusoidal signals with different frequencies each with different magnitude and phase .

Homework . 10 AND 11 announced today.. HW 10 due the Thursday after break.. MULTIPLEXING. Introduction of Multiplexing. Whenever the transmission capacity of the medium linking two device is greater than the transmission needs of the device, the link can be shared.. As a large water pipe can carry water to several separate house at once.. Multiplexing refer to the combination of information streams from multiple sources for transmission over a shared medium. Multiplexor is a mechanism that implements the concept. . Demultiplexing. refer to the separation of a combination back into separate information streams. At the end of yesterday, we addressed the case of using the dot product to determine the angles between vectors. Similar to equations from algebra, we can talk about relationship of vectors as well.

Most common use of multiplexing is in long-haul communication using coaxial cable, microwave and optical . The process of combining the data streams is known as multiplexing and hardware used for multiplexing is known as a multiplexer.. Multiplexing is achieved by using a device called Multiplexer (.
