Performance.. Introduction. Under the simplest conditions, a medium can carry only one signal at any moment in time. For multiple signals to share one medium, the medium must somehow be divided, giving each signal a portion of the total bandwidth.. . Digital Modulation and Multiplexing. NRZ and NRZI and Balanced Signals. NRZ has a positive voltage represented by 1 and a negative voltage represent by 0.. NRZI has a transition represented by 1 and a 0 represents no transition..

Most common use of multiplexing is in long-haul communication using coaxial cable, microwave and optical . 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 . 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 (. MUX.
