A method for converting an analogue signal representing a runlength limited binary signal with runs of length of at least N into a binary output signal. The analogue signal is sampled and an intermediary binary signal is generated based on the sample analogue signal. Those binary sequences within the intermediary binary signal having a length greater than 2N-1 are identified. The sequences having a set of successive samples having the same binary value, and which borders on samples having an opposite binary value. For each such binary sequence, an analogue sequence is selected in the sampled analogue input signal which corresponds to the identified binary sequence. Then it is determined if there are a plurality of significant local extrema within the selected analogue sequence, and if they are found, the identified binary sequence is partitioned into a corresponding plurality of smaller runs, comprising at least one run of length N.
