Claim 8:
9. The filtering cable according to claim 7, wherein if the value of N is 1, and the preset filter circuit comprises a band-stop filter circuit;
the etching pattern comprises: a plurality of eighth patterns; the eighth patterns comprise: a twelfth hollow line segment in the radial direction of the filtering cable; both ends of the twelfth hollow line segment are provided with a third single-ring hollow pattern, respectively; the third single-ring hollow pattern has a non-hollow area on the side close to the twelfth hollow line segment;
alternatively, the etching pattern comprises: a plurality of ninth patterns; the ninth patterns comprise: a thirteenth hollow line segment provided in the radial direction of the filtering cable, a third spiral hollow pattern is provided at one end of the thirteenth hollow line segment, and a fourth spiral hollow pattern is provided at the other end thereof; the third spiral hollow pattern is asymmetrical with the fourth spiral hollow pattern; alternatively, the etching pattern comprises: a plurality of tenth patterns; the tenth patterns comprise: a fourteenth hollow line segment and a fifteenth hollow line segment spaced side by side in the axial direction of the filtering cable; a sixteenth hollow line segment provided between the fourteenth hollow line segment and the fifteenth hollow line segment in the radial direction of the filtering cable; the middle of the fourteenth hollow line segment is communicated with the middle of the fifteenth hollow line segment through the sixteenth hollow line segment; a third single-ring hollow pattern is provided between the fourteenth hollow line segment and the fifteenth hollow line segment and at both sides of the sixteenth hollow line segment; the middle of the side of the third single-ring hollow pattern close to the sixteenth hollow line segment is provided with a non-hollow area; alternatively, the etching pattern comprises: a plurality of eleventh patterns; the eleventh patterns comprise: a rectangular fourth single-ring hollow pattern; one pair of sides of the fourth single-ring hollow pattern are provided in the radial direction of the filtering cable, and the other pair of sides thereof is provided in the axial direction of the filtering cable; a seventeenth hollow line segment is provided outside the fourth single-ring hollow pattern, and at both ends of and the middle of one pair of sides provided in the axial direction of the filtering cable, respectively; one end of the seventeenth hollow line segment is communicated with the fourth single-ring hollow pattern; two symmetric L-shaped hollow patterns are provided between the two seventeenth hollow line segments; the corner of the L-shaped hollow pattern is close to the fourth single-ring hollow pattern, one side thereof is close to the seventeenth hollow line segment, is provided in the radial direction of the filtering cable, and is communicated with the close seventeenth hollow line segment through the hollow line segment which is provided in the axial direction of the filtering cable, and the other side thereof is close to the fourth single-ring hollow pattern and is provided in the axial direction of the filtering cable; the area of the core wire corresponding to the fourth single-ring hollow pattern is provided with a through-hole in the radial direction of the filtering cable.
