A digital measuring instrument employs a sampling rate of 100 samples/second. The sampled input x(n) is averaged using the difference equation: Y (n) = For a step input, the maximum time taken for the output to reach the final value after the input transition is

Correct Answer: x (n)+x (n-1)+x(n-2)+x(n-4)/4
Since output y depends on input, such as no delay, delay by 1 unit, and delay by 2 unit, delay by 4 unit, so it will sum all the samples after 4 Ts (maximum delay), to get one sample of y. T =40 msec.

An electronic device rearranges numbers step-by-step in a particular order according to set of rules. The device stops when the final result is obtained.

4. A minimum rate of remuneration to apply in the case of employees employed on piece work for the purpose of securing to such employees a minimum rate of wages on a time work basis is overtime rate.

Which of the following are the drawbacks of acceptance sampling? (i) Acceptance sampling is less expensive. (ii) Acceptance sampling has the risk of accepting good lots and rejecting bad lots. (iii) Acceptance sampling requires planning and documentation of the acceptance-sampling procedure whereas 100% inspection does not. (iv) Acceptance sampling requires less manpower.

In a class there are 20 juniors, 15 seniors and 5 graduate students. If the junior averaged 65 in the midterm exam, the senior averaged 70 and the graduate students averaged 91, then what is the mean of the centre class approximately?

Consider the following statements: 1. The delay time is the time required to reach 50% of the final value in the first time. 2. The rise time is the time required for the response to rise from 10% to 90% of its final value for underdamped systems. 3. The rise time is the time required for the response to rise from 0 to 100% for the underdamped systems. Which of these statements are correct?
