1EE4367 Telecom. Switching & TransmissionProf. Murat TorlakIntroduction to Digital ModulationIntroduction to Digital ModulationEE4367 Telecom. Switching & TransmissionProf. Murat TorlakIntroductionIntroduction In a Digital communication system, the source to be transmitted is discrete both in time and amplitude Digital information carrying signals must be first converted to an analog waveform prior to transmission At the receiving end, analog signals are converted back to a Digital format before presentation to the end user The conversion process at the transmitting end is known as Modulation The receiving end is known as demodulation or detection2EE4367 Telecom.

3N/4 combinations have akak+1 =0 and only N/4 combinations have non zero akak+1. Because of the bipolar rule, the bit sequence 11 can only be encoded by two consecutive pulse of opposite polarities. This means the product akak+1 = -1 for the N/4 combinations. EE4367 Telecom. Switching & Transmission

Transmission over fiber is limited by the attenuation and dispersion. Multimode fibers may experience Multimode dispersion: The delayed rays cause pulse spreading Chromatic dispersion: Individual wavelengths may travel at different speeds. Dispersion creates an inherent operational limit defined as EE4367 Telecom.
