How can we generate a periodic signal from a periodic signal itself?

How can we generate a periodic signal from a periodic signal itself? Explanation: A periodic signal x(t) can be generated by a periodic extension of any segment of x of duration T( the period).

Is the sampled signal periodic?

One of the basic DSP principles states that a sampled time signal has a periodic spectrum with period equal to the sample rate.

How do periodic and aperiodic signals differ from each other?

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 the period of aperiodic signal?

A signal that does not repeat itself after a specific interval of time is called an aperiodic signal. By applying a limiting process, the signal can be expressed as a continuous sum (or integral) of everlasting exponentials.
