Which of the following operation has to be performed to increase the sampling rate by an integer factor I?
A. Interpolating I+1 new samples B. Interpolating I-1 new samples C. Extrapolating I+1 new samples D. Extrapolating I-1 new samples
Explanation: An increase in the sampling rate by an integer factor of I can be accomplished by interpolating I-1 new samples between successive values of the signal.
