What is Amplitude vs Frequency Spectrum Explained about?

The amplitude spectrum shows the amplitude of different frequency components of a signal, while the frequency spectrum shows the power or magnitude present at different frequencies. The frequency spectrum is obtained by taking the Fourier transform of a signal, which reveals the underlying periodic components and harmonics. Specifically, the frequency spectrum is the magnitude squared of the Fourier transform, while the power spectral density (PSD) describes the actual power present per unit frequency.
