Abstract

PURPOSE:To secure the steady transmission for the coding signals through the encoding system featuring the DC component by converting the low frequency component of the signals to be transmitted into the high frequency component and thus converting the signal showing the gentle change into the signal showing the sudden change. CONSTITUTION:The input analog information signals are converted into the digital signals through A/D converter 34 and then transmitted after encoding through digital code arrangement unit 35 to be applied to digital code arrangement unit 40 at the reception side via transmission system 36 for encoding. This encoded output is applied to A/D converter 41 to reproduce the analog signals. In this case, change- over switch 32 and inverse amplifier 33 are provided to the input of the analog signal at the transmission side to inverse the polarity of the signals to be transmitted by the output given every fixed time from FF38. At the same time, change-over switch 42 and inverse amplifier 43 are provided to the output of A/D converter 41 at the reception side to return the signals of the inverted polarity to the original polarity.
