Description

one

The invention of relativity; it’s to radio signal generation devices can be used in various radio engineering devices.

According to the main author. St. No. 477515, a device for shaping and signaling multi-frequency frequency-phase manipulation is known, containing a source of a multi-point code, connected via a switch to the inputs of the total and differential mixers, the outputs of which are connected to the inputs of the key circuit, as well as the control trigger.

However, the known device transmits little information.

The purpose of the invention is to increase the amount of information transmitted.

For this purpose, a device for generating signals of multi-frequency frequency-phase manipulation, containing a source of a multi-position code, connected via a switch to the inputs of total and differential mixers, the outputs of which are connected to the inputs of the key circuit, and also a control trigger, two code signal generators, phase manipulators are introduced and the key, the control input of which is connected to the corresponding control trigger output, and the information is 1OH; s: the inputs are connected to the outputs of the manipulators, while the outputs of the control trigger The phenomena are connected to the control inputs of the generator L, code signals, the sync inputs (which are connected to the corresponding; 1 ;;. - input of the switch, and the outputs of the code signal generators are connected to the information inputs of the corresponding manipulators, and the key output is connected to the control inputs of the total -: differential mixer, and a signal is sent to the control inputs of 1 tori (., the generator of oscillations of the frequency-carrying circuit.

The block diagram of the device shown in the drawing.

A device for forming: 1and signals of a multipositional frequency - phase control contains a source of a multi-position code Ij connected through a switch; - torus 2 with inputs-total 3 and the Horq 4 mixers, the outputs of which are connected to the inputs of key circuit 5, control trigger 6, code signal generators 7, 8, phase manipulators 9, 1 O, and key 11.

The control input of the key 11 is connected to the corresponding output of the control trigger 6, and the information inputs to the outputs of the phase manipulators 9 and 10. The outputs of the trigger 6 are connected to the control inputs of the code signal generators 7.8, the synchronization inputs of which are connected to the corresponding input of the switch 2, and the outputs of the generators 7, 8 are connected to the information inputs of the corresponding phase switches 9 and 10. The output of the key 11 is connected to the control inputs of the total 3 and differential 4 mixers, and to the control inputs of the switches 9 and 10 a signal is provided from a carrier oscillator.

The device works as follows.

When any of the outputs (even or odd) appear on the source of the multi-position code 1 of the code parcel, the switch 2 switches the clock frequency signals to one of its outputs. Accordingly, at the outputs of total 3 and differential 4 mixers, signals of total and differential frequencies appear. Key scheme 5 and key 11 are controlled by a trigger. 6,

At the same time, code signal generators 7 and 8 are switched by controlling their voltage from the outputs of trigger 6.

Thus, when the code signal generator 7 is turned on, the sum frequency signal appears at the output of the key circuit 5, and when the code signal generator 8 is turned on, the difference frequency signal appears. The phase m. Manipulation of the sum and difference signals is determined by

responsibly phase manipulators

9 and Y. The clock frequency multiples of the carrier frequency are used to control the source of multi-point code 1 and code signal generators 7 and 8.

This device, compared to

known, conveys much more information.
