Is amplitude and magnitude the same thing?
Amplitude and magnitude are both terms used to describe properties of quantities. The main difference between amplitude and magnitude is that amplitude refers to the furthest values that a quantity can take from 0 whereas magnitude refers to the size of a quantity regardless of direction.
What is a magnitude spectrum?
The magnitude spectrum of a filter is equal to the magnitude of the filter's transfer function (i.e., frequency spectrum). Because the vector e − i 2 π f Δ t \displaystyle e^-i2\pi f\Delta t has unit magnitude, we see that the magnitude spectrum of the unit-delay filter is 1.
Does an amplitude spectrum contribute more than a phase spectrum to the image reconstruction?
In other words, a given amplitude spectrum is more representative of an image category than a given phase spectrum, which is representative of only the corresponding given image exemplar.
How do you find the magnitude of a spectrum?
The rectangular window is the signal y(t) = u(t + 1) − u(t − 1). Use MATLAB to compute the magnitude spectrum of x(t) and y(t) and indicate which is the smoother of the two by considering the presence of high frequencies as an indication of roughness.
