What does the amplitude spectrum tell us?

The amplitude spectrum simply gives amplitude at each frequency. The phase spectrum simply gives the phase at each frequency (Figure 2.20).

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.

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.

What is meant by phase spectrum and magnitude spectrum give comparison?

The magnitude spectrum tells you how strong are the harmonics in a image and the phase spectrum tells where this harmonic lies in space.
