What is a periodic spectrum?

The Spectrum of Periodic Signals. Signals dwell both in the time and frequency domains; we can equally ac- curately think of them as values changing in time (time domain), or as blendings of fundamental frequencies (spectral domain).

How do you know if a signal is periodic or spectrum?

A signal is said to be periodic signal if it has a definite pattern and repeats itself at a regular interval of time. Whereas, the signal which does not at the regular interval of time is known as an aperiodic signal or non-periodic signal.

What is a characteristic of the spectrum of periodic signals?

periodic signal is fully characterized by a single cycle. Figure 5 illustrates the Fourier analysis of a periodic signal (including multiple cycles) and the Fourier analysis of a single cycle. All non-zero values in the spectrum of a periodic signal are captured by the spectrum of a single cycle. ...

What is an example of a periodic signal?

Examples of periodic signals include the sinusoidal signals and periodically repeated non-sinusoidal signals, such as the rectangular pulse sequences used in radar.
