FIELD: radio communications. ^ SUBSTANCE: device has signals normalization block 1, demodulator 2, signals comparison block 3, support level block 4, logical processing and modulation type indication block 5. Block 4 and 5 are made at analog comparator, on first, second and third support inputs of which threshold voltage U1, U2, U3 are fed and five logical elements AND-NO, to inputs of which voltage is fed from outputs of analog comparator, and to outputs of three of them modulation type indication elements are connected. Block 5 for decreasing number of bodies therein is made on three XOR elements with open collector output. ^ EFFECT: broader functional capabilities. ^ 2 cl, 3 dwg, 2 tbl |
