Abstract:
Provided is a signal transmission device including a first modulation unit generating a first modulated signal having at least three logic levels by modulating an input signal; a characteristic adjustment unit generating an adjusted first modulated signal by adjusting the at least one of electrical characteristic values based on an adjustment signal; a second modulation unit generating a second modulated signal by modulating the adjusted first modulated signal; and an adjustment operation unit generating the adjustment signal based on electrical characteristic values respectively corresponding to the at least three logic levels of the first modulated signal and corresponding to at least three logic levels of the second modulated signal. Linearity of the modulated signal generated by the provided signal transmission device is enhanced.
