ADC Types EE174 SJSU Tan Nguyen A continuoustime signal x t with frequencies no higher than f max can be reconstructed from its samples x n x nT s if the samples are taken at a proper sampling frequency .

The sampling rate should be at least twice the bandwidth of the signal, in order to fully reconstruct the signal.. SAI India. September 2011. Sampling is used by SAI-India extensively in.

Why is this so important?. A REPRESENTATIVE SAMPLE!. It is important that the sample selected be representative of the population from which it is taken so that inferences about the population are the best that they can be.. Probability Sampling Methods. Sampling is perhaps the most important step in assuring that good quality aggregates are being used on INDOT contracts. Since a sample is just a small portion of the total material, the importance th MTH . 494. LECTURE-13. Ossam Chohan. Assistant Professor. CIIT Abbottabad. 2. STRATIFIED SAMPLING. 3.
