"WebThe CAN protocol has defined a recessive (logic ‘1’) and dominant (logic ‘0’) state to implement a non-destructive bit-wise arbitration scheme. It is this arbitra-tion methodology that is affected most by propagation delays. Each node involved with arbitration must be able to sample each bit level within the same bit time.
