Abstract
A signal processing method of processing frequency domain signal data is described. The signal processing method includes at least the steps of applying, by the signal processing circuit, a first window function and a second window function to frequency domain signal data, thereby obtaining first modified signal data and second modified signal data, wherein the second window function is different from the first window function. The modified signal data can then be transformed into time domain. The signal processing circuit or other circuitry, such as a visualization circuit, may then generate joint visualization data based on the first transformed signal data and based on the second transformed signal data, wherein the joint visualization data comprises information on both the first transformed signal data and the second transformed signal data. Further, a measurement instrument is described.
