0 // g. The invention relates to electronics and can be used in pulsed radio navigation systems. According to the main auth. No. 311392, a device for generating a signal is known, which contains an adder, one of the inputs of which is connected to the input bus of the device via an attenuator, and the other via a series-connected tunable differentiating circuit and inverter 11). A disadvantage of the known device is the impossibility of forming a video signal with a characteristic point around the bend (CTO :). The purpose of the invention is to expand the functionality. The goal is achieved by the fact that a limiting amplifier, is inserted in the device for forming a signal containing an adder, one of the inputs of which is connected to the input bus of the device via an attenuator and the other through a circuit; a sequential connection between the tunable differentiating circuit and an inverter. the driver of the reference signal and the phase detector, the signal input of which is connected via an amplifier-limiter to the output of the adder, and its control input through the driver of the reference signal is connected to the input of the attenuator. Fig, 1 shows the functionality

on the device diagram; in fig. 2 timing charts of signals at individual points.

A device for generating a signal contains an adder 1, one of the inputs of which is connected to the input bus 2 of the device via an attenuator 3, and the other through a series-connected tunable series

nuyu. On the output bus 10, a binary quantized radio pulse with an XTO is formed, and S on the output bus 11 is a binary quantized radio pulse without an XTO.

In this way, the signal conditioning apparatus allows the formation of a video signal with a characteristic envelope point and a radio signal with a characteristic envelope point. 9 .i of the differentiating circuit 4 and inverter fopa 5, phase detector 6, the signal input of which is connected through the amplifier-limiter 7 to the output of the adder I, and its control input through the driver 8 of the reference signal-. la connected to the input of the attenuator 3. The device operates as follows. From the input bus 2 (FIG. 2, the input radio pulse arrives at the first input of the adder 1, attenuated the required number of times by the attenuator 3, the second input of the adder 1 passes the i radio pulse, inverted using an inverter 5, in the differentiating circuit 4 the frequencies of the spectrum are suppressed output signal to the carrier frequency, except for those that emphasize the steepness of the envelope. At the output of the adder 1, we receive a differential signal from the BIHK carrier at the first and second input (Fig. 2, f with XTO tpx, which, after passing through the limiting amplifier 7 pr It takes the shape of the curve shown in Fig. 2. After the radio pulse passes through the shaper 8, the signal shown by the curve in Fig. 2 g is formed. The signals from the shaper 8 and the amplifier of the limiter 7 arrive at the inputs of the phase detector 6. When the phases of these signals coincide on its output bus 9 a signal is generated (Fig. 2, d with a characteristic point of the video pulse t, - where the phase changes to the opposite of the OGLSHLG
