FIELD: radio communications, possible use in radio stations and at receiving centers for automation of search for receiving channels free of interference. ^ SUBSTANCE: device contains receiver, commutation of radio frequencies, AND element, delay line, trigger, main analysis time block, block for generating time for analyzing inverse element, interference selection block, block for generation of standard signal, attenuator, key, block for memorizing quality of signals with extrapolator, subtracter, adder, comparison block and encoder. Device may be additionally fitted with cycle counter, numbers indicator, two distributors, multiplexers, memory block, subtracter, adder and two dividers. After one cycle of analysis of all channels selection of best channel in current time moment is performed among them. When extrapolation is enabled, renewal and correction of extrapolation is performed after each cycle of analysis of all channels. ^ EFFECT: increased precision when selecting optimal channel. ^ 2 cl, 3 dwg |
