Assertion (A): Nyquist rate of sampling is the theoretical minimum sampling rate at which the signal can be sampled and still be reconstructed from its samples. Reason (R): When the Nyquist rate sampling is used, only an ideal low pass filter can be used to extract signal x(t) from sampled signal xs(t). Code:
Match the items in List - I (Techniques of sampling) with that of List - II (characteristics of procedure). Choose appropriate code for your answer : Set - I (Techniques of sampling) Set – II           (Characteristics of procedure) (a) Purposive sampling (i) Dividing the population into subgroups and taking one or more groups at random (b) Multistage sampling (ii) Researcher relies on his or her own judgment when choosing members from the population (c) Systematic sampling   (iii) Obtaining K ‘interval’ through N/n and using it for constituting the sample (d) Stratified sampling   (iv) Researcher divides the entire population into homogeneous subgroups and randomly selects the final sample

The value of the expression:sin21° + sin211° + sin221° + sin231° + sin241° + sin245° + sin249° + sin259° + sin269° + sin279° + sin289° is?
List I List II Sampling techniques used in research Description A. Simple random sampling I. The units are identified in terms of various specific features identified before drawing a sample structure B. Systematic sampling II. Each unit is given an equal independent chance of being picked up C. Dimensional sampling III. The k – interval is obtained by N/n and the units are drawn using the same, where N is population size and n is desired sample size. D. Snowball sampling IV. First member unit is used to identify the second unit and so on   Choose the correct answer from the options given below:
