The terminal resistance of the CAN bus is generally 120 ohms. In fact, during the design phase, it consists of two 60 ohm resistors connected in series. There are typically two 120Ω nodes on the bus, which is a basic understanding for anyone who knows a little about CAN bus.However, as a struggling student, I … Read more
When transmitting voltage signals over an electrical network, if the impedance at the end of the transmission line suddenly becomes infinite, the voltage signal will cause reflections at that point. The reflected signal superimposes on the normal signal, affecting communication. To eliminate such reflections, a terminal resistor that matches the characteristic impedance of the cable … Read more
