Abstract
The utility model discloses a coding and decoding display circuit for teaching. The circuit comprises a coding circuit and a decoding display circuit. The coding circuit comprises a switch S1 and an encoder CD4532. The decoding display circuit comprises a seven-segment latch decoder CD4511 and a nixie tube LG5011AH. The switch S1 is connected to the input terminal of the encoder, the output enabling terminal E0 of the encoder is connected to the blanking function terminal BI of the seven-segment latch decoder via a NAND gate CD4011, and the output terminal of the seven-segment latch decoder is connected to the nixie tube LG5011AH. The coding and decoding display circuit is advantageous in that, the encoder and the decoder are applied in a concrete display circuit, and a student can freely build the concrete display circuit according to logic functions of the encoder and the decoder. Via operation of a practical application circuit, functions of the encoder and the decoder are better grasped and learned, learning interest and manipulative ability of a student are improved, and the requirement of a modern teaching mode is satisfied.
Description
Technical field
The utility model relates to a kind of teaching coding&decoding display circuit.
Background technology
In digital circuitry, the function of volume, code translator is that a kind of digit conversion is become to another kind of digital; Compile, the output state of code translator is the result of the various combinations of its input variable, compiles, the output of code translator both can operate or other parts of control system, also can driving display, realize the demonstration of numeral, symbol.
And at present, for the study of digital circuit scrambler and code translator, giving lessons in most classroom is all to carry out impart knowledge by theory explaination, so just cause student only to know the logic function of scrambler and code translator, and do not know how it is specifically applied in actual circuit, such teaching pattern lacks learning interest for student, does not utilize raising the actual of student to start and functipnal capability, also can not meet current teaching requirement and theory simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of application circuit of being convenient to scrambler and code translator teaching use, i.e. a kind of teaching coding&decoding display circuit.
In order to address the above problem, the technical solution adopted in the utility model is: coding&decoding display circuit is used in a kind of teaching, and this circuit is by coding circuit and coding display the electric circuit constitute; Described coding circuit forms encoder circuit by switch S 1 and scrambler CD4532; Described coding display circuit is comprised of seven sections of latch decoder CD4511 and charactron LG5011AH; Described switch S 1 is connected with the input end of scrambler CD4532, the output enable end E0 of scrambler CD4532 is connected with the blanking function end BI of seven sections of latch decoder CD4511 by Sheffer stroke gate CD4011, and the output terminal of described seven sections of latch decoder CD4511 is connected with charactron LG5011AH.
Described switch S 1 is eight groups of switches.
Described charactron LG5011AH is LED charactron.
Compared with prior art: scrambler and code translator are applied in concrete display circuit, student can freely build concrete display circuit according to the logic function of scrambler and code translator, by the operation of practical application circuit better being grasped and is understood the function of scrambler and code translator, improve student's learning interest and manipulative ability, also met the requirement of Modern Teaching Mode simultaneously.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, coding&decoding display circuit is used in a kind of teaching, and this circuit is by coding circuit and coding display the electric circuit constitute; Described coding circuit is comprised of switch S 1 and scrambler CD4532; Described coding display circuit is comprised of seven sections of latch decoder CD4511 and charactron LG5011AH; Described switch S 1 is connected with the input end of scrambler CD4532, the output enable end E0 of scrambler CD4532 is connected with the blanking function end BI of seven sections of latch decoder CD4511 by Sheffer stroke gate CD4011, and the output terminal of described seven sections of latch decoder CD4511 is connected with charactron LG5011AH.
Described switch S 1 is eight groups of switches, and described charactron LG5011AH is LED charactron.
Its principle of work is: when 8 groups of switches of switch S 1 are during in on-state, 8 input end D0～D7 of scrambler CD4532 are low level, i.e. " 0 " state, 15 foots of scrambler CD4532 are high level, it is one state, 4 foots that make CD4511 after Sheffer stroke gate CD4011 are high level, i.e. one state, and charactron LG5011AH is in hidden state.
When one of them switch opens, the corresponding input end of scrambler CD4532 is high level, it is one state, scrambler CD4532 is compiled as corresponding binary code exports seven sections of latch decoder CD4511 of BCD to, converts corresponding seven segment code to and demonstrate corresponding switch number by charactron LG5011AH after decoding.
For example, while: when the 4th group of K switch 3(4～13 of switch S 1) disconnecting, the D3 input end of scrambler CD4532 is high level " 1 ", encoded device CD4532 encodes, output Binary Zero 11, deliver to seven sections of latch decoder CD4511, after decoding, export corresponding seven segment code 1111001 and deliver to charactron LG5011AH, charactron shows " 3 ".
Scrambler and code translator are applied in concrete display circuit, student can freely build concrete display circuit according to the logic function of scrambler and code translator, by the operation of practical application circuit better being grasped and is understood the function of scrambler and code translator, improve student's learning interest and manipulative ability, also met the requirement of Modern Teaching Mode simultaneously.
