What does the sampling theorem tell us concerning the rate or sampling required for an analog signal?
You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).
What are the principles of sampling survey?
Three important principles of sampling survey are: 1. Principle of validity 2. Princilpe of statistical regularity 3. Principle of optimization
What are the advantages and disadvantages of acceptance sampling?
1).There may errors (Producer's and Consumer's risk) associated with the sampling. 2).The sample does not provide 100% accurate information of the condition of the bacth.
What are the advantages and disadvantages of systematic sampling in statistics?
Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
What are the Methods in writing a set?
1.listing methods 2.roster methods
What are the merits and demerits of sampling methods?
Advantages and Limitation of Sampling: 1. Sampling saves time and labour. 2. It results in reduction of cost in terms of money and manhour. 3. Sampling ends up with greater accuracy of results. 4. It has greater scope. 5. It has greater adaptability. 6. If the population is too large, or hypothetical or destroyable sampling is the only method to be used. The limitations of sampling are given below: 1. Sampling is to be done by qualified and experienced persons. Otherwise, the information will be unbelievable. 2. Sample method may give the extreme values sometimes instead of the mixed values. 3. There is the possibility of sampling errors.

Define the four different sampling techniques?
1) Simple random sampling 2) Systematic sampling 3) Stratified sampling 4) Cluster sampling 5) Probability proportional to size sampling 6) Matched random sampling 7) Quota sampling 8) Convenience sampling 9) Line-intercept sampling 10) Panel sampling
State sampling theorem?
sampling theorem is defined as , the sampling frequency should be greater than or equal to 2*maximum frequency, and the frequency should be bounded.. i,e fs=2*fmax where fs= sampling frequency
What are the methods of data communication?
Three types of methods 1-Simplex 2-Half Duplex 3-Full Duplex 4-Serial
How many methods of GDP are there?
the methods for GDP is of 3 types 1.product method 2.income method 3.expenditure method.
How many types of dog training methods?
There are 2 types of dog training methods like Negative Reinforcement and Positive Punishment. Dogs learn good behavior by being rewarded for doing well.
Types of valuation methods?
Inventory valuation methods: 1- LIFO (Last in first out) 2- FIFO (First in first out) 3 - Average Method
What is total enumeration in research?
there are two types of data collection: 1. complete/total sampling- all members of the population are measured 2. partial sampling- a proportion of members of the whole population is measured. total enumeration is preferred for certain types of data. it has a high level of accuracy and provides a complete statistical coverage over space and time.
What is targeted sampling in research studies?
I would like to sample the signal Xa(t) =1+cos(10 *pi*t) using sampling frequency fs=8 Hz. How can I calculate this? ANSWER: Your signal has a frequency component of 5hz (from the equation: 2*pi*f*t = 10*pi*t, therefore f=5). The Nyquist rate for this signal (the minimum sampling rate required to reconstruct the signal) is then 10Hz, and even at that rate the amplitude of the sampled signal will be reduced unless you can somehow synchronize the sampling with the peaks/troughs of the cosine signal. If you sample at 8Hz you will not be able to reconstruct the signal at all.
