Which of the following converters/ convert a binary number on the input to a one-hot encoding at the output? 1. 3 to 8 binary decoder 2. 8 to 3 binary decoder 3. Comparator Select the correct answer using the code given below Correct Answer 1 only

Explanation:

One hot encoding

It is a technique, where categorical data is coded with a group of bits among the legal combinations of values, are only those with a single high (1) and all other are low bits (0).

Similar representation where all bits are (0) except one bit which is high (1) is called as “ one-cold”

In statistics, dummy variables represent a similar technique for representing categorical data.

Advantages:

  • Determining the state has a low and constant cost of accessing one flipflop
  • Changing the state has a constant cost of accessing two flipflops.
  • Easy to design and modify
  • Easy to detect all illegal states

 

Disadvantages: Requires more flipflops than other encodings, making it impractical for PAL devices

A system provides output yi(t) when xi(t) is applied. If the system is said to be LTI then which of the following properties must satisfy? (i).If the input is x3 = ax1(t) + bx2(t), then output must be y3(t) = ay1(t) + by2(t) (ii).If the input is x(t – T), then the output must be y (t – T) (iii).If the input is x3 = ax1(t) + bx2(t), then output must be y3(t) = ay1(t) * by2(t) (iv).If the input is x(t – T), then the output must be y(t + T)
In the question one statement is given, followed by two conclusions, I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statement. Statement: A function is a relation between a set of input elements and a set of possible output elements where each input is related to exactly one output. Conclusion I: Every input element is related to every output element. Conclusion II: Every input element is related to one element of the output.
Which of the following statements is/are correct? 1. A system is said to be Finite Impulse Response (FIR), if the output samples of the system depend only on the present input and a finite number of past or previous input samples. 2. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a non-recursive system. 3. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a recursive system.

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.
