Acquisition process by analog signal sampling, and an acquisition system to implement such a process

摘要

An acquisition process for signal sampling includes high-speed analog signal sampling, storing the samples of the analog signal in a matrix of memory cells, and re-reading the samples from the cells at low speed. Two identical memory devices are provided in each memory cell. One sample of an analog signal is stored in one memory device, and one sample of that signal that is out of phase is stored in the other memory device.
