FIELD: radio engineering and communications.
SUBSTANCE: invention can be used in radar and sonar, in measuring equipment, in communication systems, as well as to generate test and masking signals in audiometry. Digital synthesizer of noise signals comprises sensor of length of pseudorandom sequence 1, initial frequency code sensor 2, unit of adders 3, first 4 and second switches 7, shift register 5, code converter 6, first 11 and second 8 units for calculating amplitude, phase calculation unit 9, clock pulse generator 10, multiplier 12, digital to-analogue converter 13 and low-pass filter 14, as well as required connections between them.
EFFECT: generation of arbitrary amplitude-frequency characteristic of output signal.
