The envelope is compute from the zoomed spectrum signal by taking the module multiplied by 2. | The envelope is compute from the zoomed spectrum signal by taking the module multiplied by 2. | ||
This corresponds to an Hilbert transform (signal multiplied by itself but out of phase by | This corresponds to an Hilbert transform (signal multiplied by itself but out of phase by 90° ). | ||
