### EE5410 Fourier transform for Periodic signal

EE5410 Fourier transform for Periodic signal

1. The Fourier transform of a periodic signal with Fourier series coefficients {ak} can be interpreted as a train of impulses occuring at the harmonically related frequencies.

2. and for which the area of the impulse at the kth harmonic frequency kw0 is 2*PI times the kth Fourier series coefficient ak.

3. The Fourier transform of a periodic impulse train in the time domain with period T is a periodic impulse train in the frequency domain with period (2*PI)/T
