Abstract
A signal transmission system has a modulation signal converterthat generates a modulation signal using a Manchester code with a duty ratio of 50% in accordance with transmission data; a clock generatorthat generates a clock with the amount of delay with respect to the rising or falling edge of the modulation signal; and a data detectorthat generates received data by sampling the modulation signal in synchronization with the clock. Since the modulation signal convertergenerates the modulation signal by combining the Manchester code with the duty ratio of 50%, its duty ratio is always 50% independently of the transmission data, thereby preventing the DC offset of the modulation signal on the receiving side. Accordingly, it offers an advantage of achieving good communication quality with a simple circuit configuration without producing the DC offset in the modulation signal on the receiving side.
