Abstract
Apparatus for demodulation of a signal which is frequency-modulated with a data symbol sequence {d}, having a zero crossing detector (), a generator () for production of a sequence {z}, with zbeing calculated from zero crossings tand t, and having a unit () for reconstruction of the data symbol sequence {d}, which is characterized by a minimum Euclidean distance between the sequence {z} and an auxiliary sequence, with each sequence element in the auxiliary sequence being formed from convolution of the data symbol sequence {d} with a sequence {h} relating to the index k, and with the sequences {h} being functions of the times tand t.
