Point-By-Point Analysis

Point-by-point analysis is a method of continuous data analysis in which analysis occurs for each data point, point by point. Point-by-point analysis works well with computer-based real-time data acquisition. In array-based analysis, the input-analysis-output process takes place for subsets of a larger data set. The discrete stages of array-based analysis, such as buffer preparation, analysis, and output, can make array-based analysis too slow for higher speed, deterministic, real-time systems. In point-by-point analysis, the input-analysis-output process takes place continuously, in real time.

Point-by-point analysis enables you to accomplish the following tasks:

• Track and respond to real-time events.
• Connect the analysis process directly to the signal for speed and minimal data loss.
• Perform programming tasks more easily, because you do not allocate arrays and you make fewer adjustments to sampling rates.
• Synchronize analysis with data acquisition automatically, because you work with a single signal instantaneously.
