What is a transform in signals?

Transform Domain Signal Processing: Changing the representation of the signal from one form to another form by applying mathematical transformations is referred to as transform. Signal is decomposed in terms of orthogonal basis functions.

Why do we transform signals?

Transformations are useful because it makes understanding the problem easier in one domain than in another.

What is Fourier transform of a signal?

The Fourier transform is a mathematical formula that transforms a signal sampled in time or space to the same signal sampled in temporal or spatial frequency. In signal processing, the Fourier transform can reveal important characteristics of a signal, namely, its frequency components.

What is transform in MRI?

The Fourier transform is a mathematical technique that allows an MR signal to be decomposed into a sum of sine waves of different frequencies, phases, and amplitudes.
