By doing so, a differential voltage of 800 or 900 mVpp (where "pp" stands for "peak-to-peak") is generated on the bus. This is then also the nominal peak-to-peak amplitude (Vpp) of the signal that any Fieldbus device generates. lymph compresser massager

Is the CAN Bus a Digital signal or an Analog signal?

A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts.
