In the 2 to 4 line decoder, there is a total of three inputs, i.e., A 0, and A 1 and E and four outputs, i.e., Y 0, Y 1, Y 2, and Y 3. There are various types of decoders which are as follows: 2 to 4 line decoder: The produced 2 N-bit output code is equivalent to the binary information. At a time, only one input line is activated for simplicity. In simple words, the Decoder performs the reverse operation of the Encoder. The output lines define the 2 N-bit code for the binary information. The binary information is passed in the form of N input lines. Just as a side note - you can select some pervert encoding, like 'zip', 'base64', 'rot' and some of them will convert from string to string, but I believe the most common case is one that involves UTF-8/UTF-16 and string.The combinational circuit that change the binary information into 2 N output lines is known as Decoders. Then you decode a string (with selected encoding) and get brand new object of the unicode type. Then, again - you'd like to do the opposite - read string encoded in UTF-8 and treat it as an Unicode, so the \u360 would be one character, not 5. ![]() So you have to encode it (for example - in UTF-8), you call encode('utf-8') and you get a string with '\u' inside, which is perfectly printable. You can search it, split it and call any string manipulating function you like.īut there comes a time, when you'd like to print your unicode object to console or into some text file. The way it is stored by Python in memory is none of your concern. You can create some unicode object, which doesn't have any encoding set. decode('encoding') results in an unicode object and can be called on a string, encoded in given encoding. encode('encoding') results in a string object and can be called on a unicode objectĪString.
