Balanced transmission mode circuit diagram

Published:2011/7/16 9:44:00 Author:Sophia | Keyword: Balanced transmission mode

Figure is the balanced transmission mmode using twowire. This mode sends two signals with the 180 ° phase difference, and receive differeence of these two signals. Two signal lines can be offset if there is the noise between two signals. Balanced transmission is basically a low output impedance and high input impedance mode. The transmission line needs to use the two-wire shielded cable with excellent frequency characteristics and low distributed capacitance.   (View)
