SU126665A1 - Device for converting binary code numbers to decimal - Google Patents

Description

The known types of converters of binary numbers s decimal have a number of disadvantages. Matrix type converters include a large number of switches and rectifiers, which makes them cumbersome and expensive. Converters built on decoupled feedback meters require a prior conversion of the binary code of the number into a 1-layer pulse code. Modeling circuits of transducers introduce tangible additional faults, which diminishes the value of information transfer in a discrete form.

The proposed device differs from the known cost-effectiveness, compactness, reliability in operation, and the absence of additional errors. The conversion process includes the representation of the codes of binary bits in a series of pulses, which serve to indicate the bits of the decimal number. This is ensured by hard switching, diodes and delay lines in the converter circuit. The main element of the device is semiconductor diodes, delay lines and counters. Delay lines are made on one-shot, built on semiconductor triodes. The number of inputs to the circuit is equal to the number of bits of the binary number to be converted, so that each bit has its own separate channel.

The drawing shows a block diagram of a multiplier with multipliers from 1 to 9.

The operation of the device is as follows. Binary number pulses are sequentially received at the input of the decoder from the distributor through the channels, the number of which is the number of bits of the binary code in the received signal. By successively doubling the number of pulses (using LZ delay lines, where the delay time is 4), a series of pulses appears at the output of the decoder, the number of which in each series corresponds to the number of decks; Particular rg ..- .; 5 la, t. s. the binary code is converted to one. From the output of the multiplier, a series of pulses are sent to counting ycTpviiicrua of any type, which will produce a counting and indication at ;; the number of pulses ;; . For each fast and fast oddisty, before each decade of the computational ycTpoiicTBa, a CBoii multiplier is included.

The order of input of binary code bits is indifferent. With the introduction of the decay of the binary series, the first digit of the highest bit can almost always be entered directly into the meter, while this decreases the number of elements in the circuit. The required number of lines | delays and diodes are determined by numbers in decimal places, which are obtained by decoding each binary bit, i.e. multipliers in multiplier circuits. For example, a multiplier circuit with multipliers from / to 9 is necessary for the discharge of tens only when inputting 18 digits. bits and higher.
