Sampling a Digital Signal
Wolfram Demonstrations Project · 2007
Sampling data is the first step in the signal processing of wave forms coming from radar submarine detection earthquakes seismic oil exploration etc Upsampling and downsampling are the basic operations in multirate discretetime systemsThe bottom part of the figure shows upsampling and downsampling by an integer factor of the signal at the top For the upsampling process equidistant zerovalued sampl
