Appeal No. 95-1901
Application 08/088,397
generating means for generating a series of
message bits constituting a message to be
transmitted and a start word preceding the message
bits;
an encoding circuit for converting the message
bits into biphase bits having a predetermined bit
period which comprises a first and a second bit
interval and whose logic value is represented by a
pulse during one of the first and second bit
intervals; and
means for transmitting a biphase signal thus
obtained to a receiver;
wherein the encoding circuit converts the start
word into a biphase start bit having the pulse
during the first interval, said start bit being
distinguished from the other biphase bits in that
the second bit interval of the biphase start bit
is equal to the bit period of the other biphase
bits.
