Frequency Domain Characterization
of Signals
•
Sinusoid signals:
–
Can determine the period, frequency, magnitude and phase of a
sinusoid signal from a given formula or plot
•
Fourier series for periodic signals
–
Understand the meaning of Fourier series representation
–
Can calculate the Fourier series coefficients for simple signals
–
Can sketch the line spectrum from the Fourier series coefficients
–
You only need to know the double sided Fourier series
•
Fourier transform for non-periodic signals
–
Understand the meaning of the inverse Fourier transform
–
Can calculate the Fourier transform for simple signals
–
Can sketch the spectrum
–
Can determine the bandwidth of the signal from its spectrum
–
Know how to interpret a spectrogram plot
