FIELD: measurement technology, hydroacoustic engineering. SUBSTANCE: information-measuring channel has connected in series receiver 1, preamplifier 2, low frequency pass filter 3 and dynamic range compression block 4 with analogous amplifiers 11, amplitude limiter 12 and summer 13. Block 4 is connected to digit operation block 8 by analog-to-digit converter 5. Block 8 has three decoders 15,16 and 24, digital register 17, adder 19 and subtracter 22. Receiver-transmitting block 10 is connected to control block 9 which has counter 25 and decoder 26. EFFECT: more convenient device for hydroacoustic and seismic information processing. 2 tbl, 6 dwg
