What is frequency? 1. What is frequency? 2. Fourier transform defined 2. Fourier transform defined 3. Fourier series versus transform 3. Fourier series versus transform 4. Review: Transform of well known functions 4. Review: Transform of well known functions 5. Basic operations of Fourier transform 5. Basic operations of Fourier transform 1. What is frequency? 1. Sinusoids (Amplitude, fr equency, phase) Why focus on frequency? • Example: Telecom real estate • We perceive often in frequency than time, e.g. audio, Why Study Signals in the Frequency Domain? • More bandwidth (broadband) allows signal to change rapidly, i.e. higher data rate. E.g. Consider speeding up a pulse transmission • Ease of moving signals in frequency by modulation. 2. Fourier Transform and I nverse Defined2....
