1. A demodulator circuit for demodulating a received signal, the demodulator circuit comprising:
a transformation circuit which is configured to transform the received signal into a modified signal representation in which both amplitude-varying information and frequency-varying information are converted to a uniform representation; and
a processing circuit which is configured to process the modified signal representation to demodulate the received signal based on the uniform representation.
