Crossover in the models¶
In this example we will consider two simple models, the purpose of which is to demonstrate the possibility of changing the frequency of the signal through the blocks Upsample and Downsample, in the first case we will change the number of samples for specific data, this version of the model is shown in the figure below.
The second model performs all the same transformations, but works with caroms.
As we can see from the images, each block of these systems is coloured differently, which indicates the difference in the frequency of the signal at the output of each block.
Next, to visualise the results, we plot the spectra of signals from both models using the graph window in the model.
Conclusion¶
As we can see from these two charts, the use of Upsample and Downsample blocks directly affects the signal display in the frequency domain.
