What is magnitude spectrum?
The magnitude spectrum of a filter is equal to the magnitude of the filter's transfer function (i.e., frequency spectrum).
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 do you mean by phase spectrum and magnitude spectrum?
The magnitude spectrum tells you how strong are the harmonics in the signal. and. The phase spectrum tells where this harmonic lies in time domain for 1 D signal (and in space domain in case of multidimensional)
Is power spectrum same as FFT?
The PSD and FFT are tools for measuring and analyzing a signal's frequency content. The FFT transfers time data to the frequency domain, which allows engineers to view changes in frequency values. The PSD takes another step and calculates the power, or strength, of the frequency content.
