Which gate can be implemented by using a 3/8 decoder?
3 Line to 8 Line Decoder Block Diagram The circuit is designed with AND and NAND logic gates. It takes 3 binary inputs and activates one of the eight outputs. 3 to 8 line decoder circuit is also called a binary to an octal decoder.
How do you implement a function using 3/8 decoder?
A decoder with a,b as inputs and 2 outputs of decoder I.e., 2nd and 3rd connected to OR gate would give f function . A 3*8 decoder can be implemented using 2 2*4 decoder with one of input be enable for the 2 decoders .
How many select line enable line will be there in 3 * 8 decoder?
Answer: Total 8 select lines out of which one is selected. Explanation: The 3:8 decoder is also known as binary to octal converter.
How is encoder different from decoder?
Encoder circuit basically converts the applied information signal into a coded digital bit stream. Decoder performs reverse operation and recovers the original information signal from the coded bits. In case of encoder, the applied signal is the active signal input. Decoder accepts coded binary data as its input.
Can decoders be used for implementing functions?
Thus, a Decoder can be used to implement a function of n variables simply by connecting the outputs of the Decoder that correspond to the minterms of a function to a multi-input OR gate. Consider the Decoder circuit shown in Figure 7 which implements two separate functions of three variables.
How do you design a 3/8 decoder using a 4/16 decoder is it possible?
4 to 16 decoder circuit is obtained from two 3 to 8 decoder circuits or three 2 to 4 decoder circuits. When two 3 to 8 Decoder circuits are combined the enable pin acts as the input for both the decoders. When enable pin is high at one 3 to 8 decoder circuits then it is low at another 3 to 8 decoder circuit.
How many and gates are required to implement a 3/8 decoder?
Using the above expressions, the circuit of a 3 to 8 decoder can be implemented using three NOT gates and eight 3-input AND gates as shown in fig (1). The three inputs A, B and C are decoded into eight outputs, each output representing one of the midterms of the 3-input variables.
What is the use of decoder and encoder?
This is what encoders and decoders are used for. Encoders convert 2N lines of input into a code of N bits and Decoders decode the N bits into 2N lines. An encoder is a combinational circuit that converts binary information in the form of a 2N input lines into N output lines, which represent N bit code for the input.
