Description: Compare the two outputs: (a) Compute the maximum magnitude difference between samples of the two outputs. (b) Compute the average of the squared difference between the samples of the two outputs. (c) Plot the two output sequences on the same plot to compare them. Use a different plot symbol or line type for each sequence.

Key Concepts

Error Metrics

Error metrics provide quantitative references to assess the differences between two signals or outputs. They are essential in evaluating the performance of systems by measuring how far an observed result deviates from a reference or expected output.

Maximum Magnitude Difference

The maximum magnitude difference is an error metric that identifies the largest absolute deviation between corresponding samples of two outputs. It reflects the worst-case scenario and is critical when ensuring that none of the discrepancies exceed a predetermined tolerance.

Mean Squared Error

Mean squared error (MSE) is an error metric computed by averaging the squares of the differences between corresponding samples of two outputs. This measure emphasizes larger errors and is widely used to understand the overall quality of signal approximation or system performance.

Graphical Analysis

Graphical analysis involves visualizing data to compare outputs effectively. By plotting the sequences on the same graph with distinct markers or line types, one can intuitively observe differences, trends, and anomalies that might not be immediately visible using numerical error metrics alone.
