Abstract
A high frequency oscillatory signal is added to the gradient waveform to provide a blurring or convolution prior to sampling. The received signal can be modulated to provide the desired space-limiting function and thus avoid aliasing. The received signal is filtered prior to sampling to remove these high frequency signals.
