摘要：The present invention provides a pulse modulating method which ensuresdemodulation of bit data without being affected by a change in the pulse width andpermits high-speed transmission, pulse modulating equipment for the pulse modulatingmethod and pulse demodulating equipment. The pulse modulating equipment divides aninput signal into n-bit words and converts it into a pulse unit signal which represents thestate of the bit data for each word by time intervals i and j between odd-numberedtransitions and between even-numbered transitions. The respective time intervals i and jare free from the influence of the transmission line used, for example, and remainsunchanged in the pulse demodulating equipment, so that no demodulation error arises.Further, since the bit data is represented by the time intervals i and j between the odd-numbered transitions and between the even-numbered transitions, the coding efficiencyincreases, permitting high-speed transmission.
