The capacitance of the wire: Theoretically speaking, the capacitance of the wire is a serious influence on the transmission of high frequency as much as possible. In actual use, this capacitance value requires special control. For example, Sony's color TV, the picture is relatively sharp, of course, people generally do not want to use a very low capacitance value S line to connect the signal, so that the picture is more sharp, then you should choose a wire with a slightly larger capacitance value, according to the designer's experience and summary The product characteristics of the famous line factory, the ratio of the resistance of the variable frequency signal to the attenuation of the capacitance is generally controlled between 1:2.5 and 1:4 for the small current type of wire. Such an audio wire shows a relatively balanced sound in the audio material. (ie generally 40-80PPM)
