Summary:A hearing aid (40) comprising a frequency: shift: keying (FSK) receiver (30) comprising a first amplifier stage (13), a limiter stage (14) and a plurality of phase detection stages, wherein each phase detection stage comprises a local oscillator (15a, 15b, 15c, 15d, 15e), a mixer stage (16a, 16b, 16c, 16d, 16e), a filter stage (17a, 17b, 17c, 17d, 17e), and a comparator stage (18a, 18b, 18c, 18d, 18e), respectively. The number of phase detection stages is greater than two. The output of each comparator stage (18a, 18b, 18c, 18d, 18e) is commonly connected to the input of a look: up table (28). The invention also provides an FSK receiver for use in a hearing aid and a method for processing an FSK signal.
