What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
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.
Which is better sampling designscientific or non-scientific?

Why is core sampling needed?

Modern scientific polling uses sampling to get accurate statistics on public opinion?
Modern scientific polling uses sampling to get accurate statistics on public opinion. The sample is of the public is taken to represent the opinion of the larger public. This has become a proven and accurate way of conducting polls from the public.
Which of the following scientific procedures is most useful for helping survey researchers avoid false generalizations?
Random Sampling
George gallups four principles of accurate polling?
George Gallup's system of accurate polling included correct sampling, clear questions, and scientific principles. George Gallup also did not take funding from groups who had an interest in the outcome of the polls.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Which one is called non probability sampling a. cluster sampling b.quota sampling c. systematic sampling d. stratified sampling?
Answer is Quota sampling. Its one of the method of non-probability sampling.
