A combinational circuit like an encoder is used to perform the reverse process of the decoder. An encoder includes 2n inputs maximum and ‘n’ outputs. Therefore it encodes the data from 2n inputs into an n-bit code. It will generate a binary code that is equal to the input like active High. So, this circuit encodes 2n inputs through n-bits. Encoding is nothing but the process of changing the numbers or symbols to a coded format. A priority encoder includes a priority function that allows it to … [Read more...]
