Pleas Sep 26, 2011 · With only 4 bits you can name the device in binary and the decoder will select the correct device. Mar 9, 2016 · I am trying to build a 3-8 decoder without an enable by using two 2-4 decoders (that also don't have enables), two chips that each contain 4 AND gates, and one chip that contains 4 NOT gates. Increased Data Handling Capacity. An application for this decoder would be to convert a 4-bit binary value to its hexadecimal representation. 3. So here taking k to be 4, k is even, so we will have \$2^k\$ so \$2^4 = 16\$ AND gates & 2 decoders each of size \$2^{k/2}\$ so \$2^2 = 4\$. As previously, we can implement 4 to 16 decoder by using either two 3 to 8 decoders or five 2×4 decoders. 4×16 decoder (binary to hexadecimal converter) using 3×8 decoders.

Now it's just using these 2-to-4 decoders to make to a tree where a decoder on E[5:4] produces enables for decoders on E[3:2] which produce enables for decoders on E[1:0], similar to the 74LVC138 example above. b. design a 4 to 16 bit decoder using two 3 to 8 bit decoder. 4 to 16 decoder using 3 to 8 decoder. Construct a 4×16 decoder using two 3×8 decoders with active low outputs and one active low enable input, shown below. Users need to be registered already on the platform. Many a times, it happens that we don’t have a larger decoder, so we normally combine small decoders to design a bigger one. Q. Part B: Using 2:4 Decoders to create a 3:8 Decoder (Graded Multisim) In this part, you will construct a 3. Anil K. m2 = 16 m1 = 8 Number of lower order Answer to Design a 4-to-16 line decoder using two 3-to-8 line. Feb 11, 2013 · \$\begingroup\$ I will describe the question exactly as it is: "You are to design a combinational logic circuit with four inputs, A3, A2, A1 and A0, and one output, Z. Implement the G and E outputs using the 4×16 decoder built in (b) (b) and 2-input AND/NAND gates. For the purpose mentioned in your classroom, a 3-to-8 decoder can help you implement a 3-variable Boolean function. Fill the observed values in the Download scientific diagram | The combinational logic gate implementation for 4–16 decoder using matrix representation method from publication: A matrix representation method for decoders using Design a 4-16 line decoder using two 3 to 8 line decoders and 16 2-input AND gates.
