Abstract:
A method for the transmission of digital transmission signal between a transmitter unit (1) and at least one receiver unit (3), comprising: in the transmitter unit (1), combining at least two digital transmission signal (s.sub.11, s.sub.12 . . . s.sub.1n) to form a multilevel signal (m); transmitting the multilevel signal (m) through a signal lead (2) from the transmitter unit (1) to the receiver unit (3); in the receiver unit (3), forming digital received signals (s.sub.31, s.sub.32 . . . s.sub.3n) corresponding to the digital transmission signals (s.sub.11, s.sub.12 . . . s.sub.1n) by amplitude filtering from the multilevel signal (m); and wherein an intermediate signal (z.sub.4) formed by AND-gating a clock signal (SC) and serial data signal (SD) that is in synchronism with the clock signal (SC), is supplied to the transmitter unite (1) as a first digital transmission signal (s.sub.11) and the clock signal (SC) is supplied as a second digital transmission signal (s.sub.12).
