  • Patent number: 11796518
    Abstract: An evaluation section identifies, in a list of candidate compounds, a group of candidate compounds having the degree of reverse similarity greater than or equal to a threshold s1. When all candidates in the group of candidate compounds have differences between the degrees of similarity that are greater than or equal to a threshold s2, the evaluation section judges that there is a composite state. The difference between the degrees of similarity is computed by subtracting the degree of forward similarity from the degree of reverse similarity. The similarity ratio may be used in place of the difference between the degrees of similarity.

  • Patent number: 11480597
    Abstract: An improved analysis and determination of a relationship between a tone frequency and spurious frequencies is provided. A device under test is operated to generate signals based on multiple different tone frequencies. For each tone frequency a spectrum of the generated signal is measured and spurious frequencies in the generated signal are identified. Based on the measured spectrums a representation of the spurious frequencies versus the related tone frequencies is generated. Trajectories may be inserted into the representation for indicating relationships between the tone frequencies and the spurious frequencies. This representation provides a useful basis for a fast and reliable identification of relationships between spurious frequencies and tone frequencies.
