Part III
Picking Up the Frequency Domain
In this part . . .
Get familiar with the Fourier series to understand the composition of periodic signals in the frequency domain.
Find out how to convert time-domain signals to a frequency spectrum with the Fourier transform.
Come to grips with the applied math associated with sampling theory.
See for yourself what’s so cool about using the discrete Fourier transform to process signals by multiplication in the frequency domain.
