Cardiorespiratory Dynamic Response to Mental Stress: A Multivariate Time-Frequency Analysis

Figure 3

Averaged results of the simulation study: (a) TF spectrum 𝑆₁₁(𝑡,𝑓); (b) partial TF spectrum 𝑆_𝑥𝑥/2(𝑡,𝑓) of simulation study 1; (c) partial TF spectrum 𝑆_𝑥𝑥/2(𝑡,𝑓) of simulation study 2. In the ideal case, the partial spectrum 𝑆_𝑥𝑥/2(𝑡,𝑓) equals 𝑆₁₁(𝑡,𝑓).
