DEVICE FOR SIMULATION OF MULTIPLE-CHANNEL SYSTEM FOR INFORMATION TRANSMISSION WITH CHANNEL SEPARATION BY FREQUENCY

摘要

FIELD: computer engineering. SUBSTANCE: device has three adders 1, 10, 11, switch 2, M channels in transmitting part, each of which has signal detector 3, voltage-to-frequency converter 4 and filter 5, which are connected in series. In addition device has M channels in receiving part, each of which has filter 6, clipper 7 and demodulator 8, which are connected in series. In addition device has reference voltage unit 9, group of non-linear gates 12-1 . . . 12-K, group of M switches 13-1 ... 13-M, each of which has first and second breaking contacts which are joined mechanically. In addition device has multiplication unit 14, M-1 channels which are designed as serial circuits each of which has narrow-band filter, square detector 16, averaging unit 17, subtraction unit 18 and multiplier 19. EFFECT: increased functional capabilities due to possibility to calculate coefficient of shape and size of spectrum of overlapping noise. 3 dwg
