Study Notes
Fourier Transform Series
- A mathematical tool used to decompose a signal into its constituent frequencies, providing a frequency-domain representation of the signal.
Mathematical Representation
- The Fourier transform series is represented mathematically as: ∑[an cos(nx) + bn sin(nx)] from n=0 to ∞ where an and bn are the coefficients of the cosine and sine terms, respectively, and x is the time variable.
Signal Processing Applications
- The Fourier transform series allows us to: • Analyze signals in the frequency domain, providing insights into the signal's frequency composition. • Filter out unwanted frequencies, enabling signal denoising and signal separation. • Modulate signals, enabling communication systems such as radio and telephone transmission. • Compress signals, reducing the amount of data required to represent the signal.
