Abstract

Connection arrangement of dual band detector brings about the solution of the problem of removal of the modulation signal distortion in double-beam propagation of short-wave signal propagation in the earth-ionosphere tract. The principle of the connection arrangement of dual band detector consists in the fact that that the input clamp /1/ is connected with the squarer /2/ input and with the input of the third phaser /8/. The squarer /2/ output is connected with the shaper /3/ input; the output of the modulator divider /4/ is connected with the input of high-frequency transformer /5/. The output of the first phaser /6/ is connected with the input of the second phaser /7/, the output of the first AND circuit /9/ is connected with the output of the second AND circuit /10/. The connection arrangement of dual band detector can be utilized for reception of ionospheric short-wave signals in radio band of amplitude modulated signals.<IMAGE>
