Encoding vs. Decoding in Reading | Definition & Examples

You have been given the task of designing a decoder that detects the presence of the codes 0000, 0010,1101, 1000 and 1010 (of form Q4Q3Q2Q1). An active HIGH output is required to indicate theirpresence. Develop the minimum decoding logic with a single output that will indicate when any oneof these codes is on the inputs. For any other code, the output must be LOW. Draw the circuit that youwill use to decode these signals in the decoder box below:Q4Q3Q2Q1DecoderY (output)
