A waveform signal converting apparatus is designed to convert each of instantaneous values of an input waveform signal in accordance with desirable one of plural data conversion functions. Herein, one of plural data conversion functions is selected in response to comparison result of a comparator which compares each of instantaneous values to the reference value. This reference value can be varied in response to the comparison result of comparator and/or a varying tendency of the instantaneous values of the input waveform signal to be increased or decreased. Preferably, there is provided a memory (e.g., ROM) which pre-stores at least one data conversion table for converting the input waveform signal.
