What is the need of sampling in communication?
To convert a signal from continuous time to discrete time, a process called sampling is used. The value of the signal is measured at certain intervals in time. If the signal contains high frequency components, we will need to sample at a higher rate to avoid losing information that is in the signal.

What are the problems with sampling?
List of the Disadvantages of Purposive Sampling It provides a significant number of inferential statistical procedures that are invalid. This process is extremely prone to researcher bias. Purposive sampling is highly prone to researcher bias no matter what type of method is being used to collect data. It may be challenging to defend the representative nature of a sample.
What are the pros and cons of sampling?
Pros and Cons: External validity: Allows generalization from the sample to the population being studied. Relative speed: Faster than contacting all members of the population or simple random sampling. Limited feasibility: This sampling method is not possible without a list of all members of the population.
What are the different advantages of sampling?
Advantages of sampling Low cost of sampling. If data were to be collected for the entire population, the cost will be quite high. Less time consuming in sampling. Use of sampling takes less time also. Scope of sampling is high. Accuracy of data is high. Organization of convenience. Intensive and exhaustive data. Suitable in limited resources. Better rapport.
