1. , a kind of pick-up unit of meat quality is characterized in that, comprises CPU (central processing unit), swept-frequency signal generating unit and detecting unit;

  • Described swept-frequency signal generating unit is used for generating the sine sweep signal under the driving of described CPU (central processing unit), and the sine sweep signal that generates is exported to described detecting unit, and described sine sweep signal comprises the source signal of a plurality of frequencies;

    Described detecting unit, be used for the source signal of described a plurality of frequencies is loaded into meat to be measured, draw from the output signal of the source signal correspondence of each frequency of meat to be measured output, source signal and corresponding output signal according to each frequency draw the source signal of each frequency and the amplitude ratio of output signal, and the amplitude specific output of each frequency correspondence that will draw is given described CPU (central processing unit);

    Described CPU (central processing unit) is used for the complex impedance value according to each frequency correspondence of amplitude ratio generation of each frequency correspondence.
