A method and an apparatus for pulse signal analyzing are provided. The method includes: receiving a pulse signal； decomposing the pulse signal into a plurality of characteristics signal； generating a spectrum for each of the plurality of characteristics signal by using a spectrum projection； obtaining a plurality of quantized data for each of the plurality of characteristics signal by quantizing the spectrum corresponding to each of the plurality of characteristics signal； and determining a physiological condition corresponding to the pulse signal according to the plurality of quantized data of the plurality of characteristics signal.
