Abstract

PURPOSE:To compensate the lowering in eye height ratio, by selecting the code constitution of a framing code signal which makes possibly small the linear distortion and phase distortion received with group delay characteristics of a transmission line before the data sampling point in a receiver from a transmitter. CONSTITUTION:Framing code is selected so that a framing code FLC signal has comparatively higher frequency component, thus so that consecutive number of bits of ''1'' or ''0'' can be minimized. For example, the signal that ''1'' or ''2'' is not consecutive in >=2 bits is formed at a timing pulse forming circuit 5 from the FLC in 8- bit having the error protection function of 1-bit and for example, 00101101 is adopted, then the waveform distortion and phase distortion can possibly be minimized. Thus, the decrease in the eye height of the FLC signal can be compensated.
