This invention relates to a method of encoding data by transitions in a binary sequence, as well as to a coder and a decoder using the method. In the method data is encoded as follows: a first value bit is encoded by a transition in the middle of the corresponding bit-time, but this transition is inhibited if there was a transition in the middle of the previous bit-time, a second value bit is encoded by a transition at the beginning of the corresponding bit-time, but this transition is shifted from the beginning to the middle of the bit-time if there was a transition in the middle of the previous bit-time.
