| Abstract: | Sampling rate, quantization noise and the number of channels to be acquired, the main concepts of computerized data acquisition, are discussed as regards their relevance to clinical research. Different setups of analog/digital conversion and signal processing, such as real-time and post-acquisition mode, are contrasted with respect to performance and installation effort. Additionally, continuous analog recording on FM coded tape is presented as a useful tool for software testing, re-evaluation and backup purposes. |
