PPT-Chapter 5: Analog Transmission

Converting digital data to a bandpass analog signal is traditionally called digitaltoanalog conversion Converting a lowpass analog signal to a bandpass analog signal is traditionally called analogtoanalog conversion .

Forouzan. 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.. Computer Networks Physical Layer Based on slides from Zoltán Ács ELTE and D.
