发明名称 Arrangement for reading an information carrier
摘要 The invention relates to an arrangement for reading an information carrier (2). The arrangement comprises a read head (4) for scanning the information carrier along a scanning path. The read head thus generates one or more electric signals (VA, VB, VC, VD) in response to a physical pattern recorded along the scanning path. The arrangement comprises one or more electrical conductors (6.2, 6.3, 6.4, 6.5, 6.6) for conveying these signals to a signal processing unit (8). The electrical conductors include one or more signal conductors (6.2, 6.3, 6.5, 6.6) and at least one reference conductor (6.4). The one or more signal conductors (6.2, 6.3, 6.5, 6.6) are coupled to the at least one reference conductor (6.4) via a resistive impedance (R1, R2, R3, R4) and a capacitive impedance (C), which are connected in series.
