SUBSTANCE: generator of discrete orthogonal multilevel signals includes pacing generator, frequency splitter, Walsh function generation unit, three multiplier groups, 'NOT' element, switchboard, two control signal generation units, and amplifiers with variable amplification gain. Pacer generator output is connected to input of frequency splitter, output of which is connected to clock input of Walsh function generation unit, to first input of each multiplier of first group, and via 'NOT' element to first input of each amplifier of second group, to clock inputs of control signal generation units. Outputs of Walsh function generation unit are connected to first input of corresponding amplifier from third group, to master input of switchboard, and to data input of switchboard respectively. Switchboard output is connected to second inputs of all third group amplifiers. Output of one of the third group amplifiers is connected to second outputs of respective amplifiers from the first and second groups. Outputs of amplifiers from the first and second groups are connected to inputs of respective amplifiers with variable amplification gain. Outputs of control signal generation units are connected to master inputs of amplifiers with variable amplification gain, outputs of which are the device outputs.
