What is the minimum necessary speed?         Six computer workstations are connected to a synchronous time division multiplexor.  Each workstation transmits a 128 kbps. At any point in time, 25 percent of the workstations are not transmitting. What is the minimum necessary speed of the line leaving the multiplexor?    Will the answer be different if we use a statistical multiplexor instead?  Explain your reasoning   Synchronous TDM (definition and calculations):     Statistical TDM (definition and calculations):
