Fourier analysis is the technique of decomposing a signal into its frequency components using the Fourier transform. It can help you understand the spectral properties of a signal, such as its bandwidth, power spectrum, and harmonic content. It can also help you design and implement filters, which are devices that remove or enhance certain frequencies from a signal. Filters can be used for noise reduction, signal enhancement, frequency selection, etc. Modulation is the process of changing the frequency, amplitude, or phase of a carrier signal according to a message signal. Modulation can be used for transmitting information over a channel, such as radio waves, optical fibers, or cables.
