What is magnitude spectrum of a signal

The Magnitude Spectrum of a signal describes a signal using frequency and amplitude. That is frequency components of a periodic signal are plotted using Frequency Domain - frequencies plotted in X-axis and amplitude plotted in Y-axis.

What is meant by the spectrum of a signal?

The signal spectrum describes a signal's magnitude and phase characteristics as a function of frequency. The system spectrum describes how the system changes signal magnitude and phase as a function of frequency. For example, At the lower frequencies, below around 80 Hz, the magnitude spectrum is 1.0.

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)

How do you find the magnitude and phase spectrum of a signal?

The magnitude and phase spectra are calculated from the complex output Xf using abs(Xf) and angle(Xf), respectively (see Example 3.3). Again, the angle routine gives phase in radians so as to convert to the more commonly used degrees scale by 360/(2π).

What is magnitude spectrum DSP?

The magnitude spectrum of a filter is equal to the magnitude of the filter's transfer function (i.e., frequency spectrum).
