When someone speaks, an analog wave is created in the air. . . This can be captured by a microphone and converted to an analog signal or sampled and converted to a digital signal.. Introduction. One of the major functions of physical layer is to move data in the form of electromagnetic signals across a transmission medium.. Thus, the data must be transformed to electromagnetic signals to be transmitted.. 5 April 2020Brass TacksAn in-depth look at a radio-related topicBandwidthEvery so often the subject of bandwidthseems to come up and judging by the way most hams dismiss its significance it seems to m 1. st. semester 1440 - 2018. 2.
