Description

The invention relates to telegraphy and data transmission. Transmitting stationary devices are known, which contain a continuously operating clock pulse generator that controls the operation of the dynamic register of the actuator, the yoke, to the input.m of the corresponding bits of which the typing unit and the din are connected: my trigger is triggered, and the output is connected to one of the inputs of the output block. Improving the accuracy of converting and shaping parcels is associated with the increasing complexity of the device and reducing its operational capabilities. In the proposed device, the output of the dynamic shift register is additionally connected via an inverter to one of the inputs of the AND circuit, to the other input of which the output of the clock generator is connected, and the output is connected to the second input of the output unit. In addition, the outputs of three corresponding bits, two of which are directly, and one through the circuit "is NOT connected to the inputs of the additional circuit" PI. The output of the latter through a one-bit dynamic register is connected to one of the inputs of the dynamic trigger, the output of the corresponding dynamic shift register and an auxiliary input of the modular unit are connected to the other input of the KOTOiporo at the same time. The drawing shows the block diagram of the proposed device. The device contains a dynamic shift register 1, a dial-up unit 2, a dynamic trigger 3, a clock pulse generator 4, an output block 5, an inverter 6, an AND 7 circuit, an HE 8 circuit, an additional AND 9 circuit and a single-bit dynamic register 10. Principle device operation is as follows. On the initial setup circuit through a one-bit dynamic register 10, the device is reset, and a dynamic trigger 3 is started, which gives a series of pulses to the information request to the dial 2. The generation of a series of pulses allows the output of information by a parallel reverse code to the inputs 2, k + 2, 2k + 2, .. (n + l) k + 2 bits of the dynamic shift register 1 in the form of a burst. Simultaneously: 1 with the information on the inputs nk + l and nk + 3 bits of the dynamic shift register / a single impulse of the installation (trigger signal) is received. After k-1 clock, the setting signal from output (p-1) + 3 bits of the dynamic shift register sets the initial state of the dynamic T | rigger 3, which, with the k clock, stops supplying bridging pulses to the dial block 2 and disables the arrival of information signals in the dynamic shift register / с k + clock. In this case, each currentless information package will correspond to a series of k Empulses, and each current - a series of k zeros. From the output of the dynamic shift register, the start-and-show and the best | Va parcels in the form of a series, out of k pulses, arrive at one of the inputs of the output unit 5. Each parcel is also in the form of a series of k zeros through the investor (Rtor 6 enters the “ And the clock signal is applied to it. From the output of the circuit "And 7 series of k I1 pulses, corresponding to the current and stop sends, arrive at the second input of the output unit 5.

As information advances with clock pulses, the previously recorded trigger command 101 is shifted to the output of the dynamic shift register 1 and can be decoded at the outputs 3, 4, 5 bits through the nk-1 clock after recording. For this, the output signals from the 5th and 5th bits together with the inverted "NOT 8" signal are fourfold (twice, the rows are allocated by the additional circuit "AND 9. The selected signal is fed to the one-bit register 10 to set the device to its initial state. Installation It is performed with the nk clock, in this case the dynamic trigger 3 is triggered, at the output of which with the nk clock appears pulses allowing the input of new information with "A + 1 so.ct." The entire information transfer cycle lasts for nk + 2 beats.
