What is the number of inputs and outputs of a decoder that accepts 128 different input combinations?
A decoder that accepts 128 different input combinations requires 7 input lines, as (2^7 = 128). The number of output lines corresponds to the number of unique output combinations, which is also 128, since each input combination produces a distinct output. Therefore, the decoder will have 7 inputs and 128 outputs.

How many outputs are possible for 4 input decoder?
A 4-input decoder can produce (2^n) outputs, where (n) is the number of inputs. For a 4-input decoder, (n = 4), so the number of possible outputs is (2^4 = 16). Therefore, a 4-input decoder can generate 16 distinct output lines based on the 4 input combinations.
How many data inputs contains by a 64 output lines decoder?
A 64-output line decoder has 6 data inputs. This is because a decoder's number of outputs (N) is related to the number of inputs (n) by the formula ( N = 2^n ). Therefore, to achieve 64 outputs, you need ( n ) such that ( 2^n = 64 ), which means ( n = 6 ).
How do you make 6 to 64 decoder using four 4 to 16 and one 2 to 4 decoder?
To create a 6 to 64 decoder using four 4 to 16 decoders and one 2 to 4 decoder, first, separate the 6 input bits into two groups: the upper 2 bits (let's call them A5 and A4) and the lower 4 bits (A3 to A0). Use the 2 to 4 decoder to decode the upper 2 bits, which will select one of the four 4 to 16 decoders. Then, connect the lower 4 bits to all four 4 to 16 decoders. The selected 4 to 16 decoder will activate one of its 16 outputs based on the lower 4 bits, resulting in a total of 64 outputs from the combination of the decoders.
How does PLD connect with 7 segment decoder?
Programmable Logic Devices (PLDs) can be programmed to implement various logic functions, including those required for driving a 7-segment decoder. A 7-segment decoder takes binary input and activates specific segments to display corresponding decimal digits. By configuring a PLD, you can create the necessary logic circuits that translate binary inputs into the appropriate outputs for the segments of the display. This programmable nature allows for flexibility in design and the ability to easily modify functionality as needed.
Why the decoder one output cannot be activated more than one at one time?
In a decoder circuit, only one output is activated at a time because it is designed to represent a unique binary input combination. The logic gates within the decoder ensure that each specific input corresponds to a single output line being high (active), while all other outputs remain low (inactive). This one-hot encoding scheme prevents ambiguity and ensures clear and distinct representation of the input state, which is crucial for accurate digital processing and control.

Explain Implementation of full adder with a decoder?
A full adder can be implemented using a decoder by utilizing a 3-to-8 line decoder to decode the three input bits: A, B, and Carry-in (Cin). The decoder generates eight output lines corresponding to all possible combinations of the three inputs. The outputs of the decoder can then be combined with logic gates to derive the Sum and Carry-out outputs of the full adder. Specifically, the Sum output can be generated by ORing the appropriate outputs of the decoder, and the Carry-out can be derived from a combination of specific outputs as well.
Implement a full adder using a decoder?
A full adder can be implemented using a 3-to-8 decoder by using the sum and carry outputs of the adder as the decoder's outputs. Connect the three inputs (A, B, and Cin) to the decoder, which will activate one of its eight outputs based on the binary combination of these inputs. The sum output can be obtained by combining the appropriate activated outputs with XOR gates, while the carry output can be derived using OR gates to combine specific activated outputs. This setup allows the decoder to effectively represent the logic required for a full adder.
How does a DSTV decoder work?
The DSTV decoder connects to a Satellite Dish on the top of your house. That dish receives a digital satellite television (DSTV) signal. Your decoder then decodes this signal and outputs it into your TV.

How does a memory decoder 74Ls138 function?
The 74LS138 is a 3-to-8 line decoder that takes 3 input binary signals and activates one of eight output lines based on those inputs. It features three select inputs (A0, A1, A2) that determine which output (Y0 to Y7) will be low (active), while all other outputs remain high (inactive). The decoder also has enable inputs to control its operation; if the enables are not activated, none of the outputs will be activated. This device is commonly used in memory address decoding and data routing applications.
The description of a printer?
A printer is a machine that accepts graphic outputs from the computer and transfers the information into the paper. This can vary in sizes, sophistication, cost and speed.
How can you design 4-to-16 decoder with five 2-to-4 decoder?
It turned out to be very easy))) But I was thinking for a while to solve the problem... )))Ok. Lets say we have inputs S3..S0. Let S3 and S2 go to inputs of each of FOUR of decoders; and S1 with S0 go to the inputs of the FIFTH decoder. The four outputs of the FIFTH decoder go to enable lines of the four decoders. Voila! It might be confusing, but just draw the whole thing and you'll see. Now you just need to enable the fifth decoder... HA-HA!
What is the maximum no of output a logic gate can have?
The maximum number of outputs a standard logic gate can have is typically one. However, certain complex gates like multiplexers or decoders can have multiple outputs, depending on their design and function. For example, a 2-to-4 line decoder has four outputs, but these are derived from the combination of its inputs. In general, basic gates like AND, OR, and NOT are designed for a single output.
