What is the difference between a Fourier series and a Fourier transform?

The Fourier series is an expression of a pattern (such as an electrical waveform or signal) in terms of a group of sine or cosine waves of different frequencies and amplitude. (MORE)

What is a fast Fourier transform?

A fast Fourier transform is an efficient algorithm for working out the discrete Fourier transform - which itself is a Fourier transform on 'discrete' data, such as might be he (MORE)

What is the Fourier Transform?

The Fourier transform is a mathematical transformation used to  transform signals between time or spatial domain and frequency  domain. It is reversible. It refers to both t (MORE)

How does the graph of Fourier Series differ to the graph of Fourier Transform?

You can graph both with Energy on the y-axis and frequency on the x. Such a frequency domain graph of a fourier series will be discrete with a finite number of values correspo (MORE)

What is the difference between fourier series and fourier transform?

As it has been already hinted, Fourier Series is used for periodic signals. It represents the signal by the discrete-time sequence of basis functions with finite and concrete (MORE)

What is the fourier transform of Tan function?

tanx = 2*(sin2x - sin4x + sin6x - ... ) However, be warned that this series is very slow to converge.
