WebChoosing the proper bus-termination technique—parallel, series, Thevenin, ac, or diode-based—is critical to digital-system performance. Improper termination can lead to ringing and stair-stepping, which in turn can cause false triggering and data errors. EDN DESIGN FEATURE Parallel termination, which is the simplest type, comprises a WebThe basic rule when choosing a termination resistor is that the value of the resistor must equal the characteristic impedanceof the twisted pair cable. Termination resistor prevents signal rebound, like waves hitting a wall. The characteristic impedance of twisted pair cables is not a magic number. dialtown abel
