No, because for a signal to become periodic it must repeat itself in regular intervals of its time period.A 0 Hz signal has a time period equal to infinity , so technically the signal can never complete a full cycle by reaching infinity let alone repeat itself, since the signal is unable to repeat itself in regular intervals its not periodic.

Is DC signal is periodic?
Yes DC is periodic with zero frequency........and undefined fundamental time period To........
Is the frequency domain plot of an alarm system discreet or contineous?
discrete because the signal of an alarm is periodic.
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
What does frequency of a signal measure?
repetition rate of signal
Is DC signal is periodic?
Yes DC is periodic with zero frequency........and undefined fundamental time period To........
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
Can you say whether a signal is periodic or nonperiodic by looking at its frequency domain plot?
Yes. The Fourier transform of a signal to the frequency domain will give rise to a graph that has energy (is greater than zero) at only the base frequency and its harmonics.
What are the characteristics of a periodical?
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.

What is band limited signal?
A signal is said to be a band limited signal if all of it's frequency components are zero above a certain finite frequency. i.e it's power spectral density should be zero above the finite frequency.
Is the frequency domain plot of an alarm system discreet or contineous?
discrete because the signal of an alarm is periodic.
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
A periodic signal with a bandwidth of 70khz and highest frequency 200khz all frequencies have amplitude of 110v draw the spectrum in frequency domain utilizing Microsoft Excel charting facility?

Why a signal is called base band signal?
In signal processing, baseband describes signals and systems whose range of frequencies is measured from zero to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting at zero.
A signal has a frequency of 100 Hz and a phase of 180 degrees?
The wave has been offset from zero by 0.005 seconds
Is the bandwidth equal in each cycle of a periodic signal?
Yes, If you perform a windowed Fourier Transform of a truly periodic signal using a window function exactly one cycle wide the results will be exactly the same signal frequency spectrum, regardless of where on the signal you placed the window function. But you should also realize the results will also be the same signal frequency spectrum using a window function of any width that is an integer multiple of one cycle (greater than zero), or even without any window function at all. This signal frequency spectrum contains all the information needed to determine what is commonly called the bandwidth of the signal (and that spectrum often contains frequencies outside that bandwidth, but usually only at very low amplitudes so that their loss in filters, etc. is not generally considered significant).
