When it comes to electronic communication, they all have one main function. That is to transfer information from one spot to another. In order to do this there are many limitations a person, or rather machine, has to go through. One of the most important limitations is bandwidth. Bandwidth is pretty much the rate at which data of information is transferred. You can find the bandwidth of a communication system by subtracting the lowest- frequency signal from the highest frequency signal. It is expressed in units of Hertz (Hz). The higher the bandwidth, the more information can be passed at a particular time. R. Hartley of Bell Laboratories developed Hartley’s Law in 1928 which shows the

Unformatted text preview: relationship between information, bandwidth, and time of transmission. The equation is information bandwidth time of transmission. In words, it states information is proportional to the product of bandwidth and time of transmission. To put this in prospective, AM radio and television can be used to give an example. The bandwidth on television systems is much larger than that of AM radio systems. To be more specific the television bandwidth is about 200 times larger than AM radio bandwidth which is 30kHz. That is mainly due to the video that has to be transmitted to televisions and the amount of information in it....
