The frequency is 300/30 = 10 Hz
The time period is 30/300 = 0.10 seconds

In Fourier transformation and Fourier series which one follows periodic nature?
The Fourier series can be used to represent any periodic signal using a summation of sines and cosines of different frequencies and amplitudes. Since sines and cosines are periodic, they must form another periodic signal. Thus, the Fourier series is period in nature. The Fourier series is expanded then, to the complex plane, and can be applied to non-periodic signals. This gave rise to the Fourier transform, which represents a signal in the frequency-domain. See links.
How much time is the maximum positive current behind the maximum positive voltage when the current lags the voltage by 90 degrees?
It depends on the periodic time of the supply which, in turn, is determined by the supply frequency. So, work out the periodic time of a 50 or 60-Hz waveform, and go from there.
Why fourier series is used for frequency domain?
The fourier series relates the waveform of a periodic signal, in the time-domain, to its component sine/cosine frequency components in the frequency-domain. You can represent any periodic waverform as the infinite sum of sine waves. For instance, a square wave is the infinite sum of k * sin(k theta) / k, for all odd k, 1 to infinity. Using a Fourier Transformation, you take take a signal, convert it from time-domain to frequency-domain, apply some filtering or shifting, and convert it back to time-domain. Sometimes, this is easier than building an analog filter, even given that you need a digital signal processor to do it.
What is the period of a signal with a frequency of KHz?
1Hz is unit of frequency,which is equals to one cycle per second........................ ....................................................................................................shashi
How do you measure the frequency of a non-periodic signal?
You see how long it takes for each signal and find the average. Example: 1st: 1second 2nd: 3seconds 3rd: 2seconds. So add all and divide by how many terms (3). 1+3+2=6 6/3= 2. The frequency is 2units. I hope this is right.........
What is a periodic wave?
continuous,regular and rythmic disturbances in a medium result from periodic vibrations of a source which cause periodic waves in that medium.
What do periodic oscillations look like?
They look like blurs
What is frequency of a periodic function?
The frequency of a periodic function is 1/Period
What is the difference between underdamped and overdamped oscillations?
Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
How does frequency apply to periodic waves?
Periodic waves are characterized by a frequency, a wavelength, and by their speed.
How was velocity of a wave derived?
The velocity=distance/time ,, Suppose that the distance covered is one complete vibration therefore the distance is called wavelength and the time is called periodic time then velocity=wavelength/periodic time also frequency= 1/periodic time therefore the velocity=wavelength*frequency
How do you calculate time given frequency?
periodic time is the reciprocal of frequency , so if the frequency is 4 then the periodic time is 1/4
Is vibration having the ability to produce pulses?
Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.sorce-wikipedia
What is an oscillating massage?
An oscillating massage is simply a massage using a vibrating machine to give periodic vibrations to the areas desired. Some of the machines commonly used are a vibrating belt, chair, or mattress.
What is meant by the frequency of a periodic motion?
The frequency of a periodic motion refers to the number of cycles that are completed per second. The frequency is obtained by getting the reciprocal of the period.
What are free and forced oscillations?
In absence of any external force, the body would oscillate indefinitely with a constant amplitude a, then it is called free oscillation. When a body, being acted by an external periodic force ,oscillates with the frequency of the force, then the oscillation of the body is called forced oscillation.
What is the frequency of the waves?
Waves are constituted by periodic oscillations of some physical quantity (like pressure in matter of electric field, in this cases we talk about sound and electromagnetic waves). A superposition of different oscillations is also a wave. Let us consider a single oscillation. Since it is periodic, if we focus on the quantity on a single point, in time it has a periodic change. The wave frequency is by definition the inverse of the period of this change, that is the inverse of the time elapsed between two consecutive instant where the considered quantity has the same values in the same point. A wave constituted by a single oscillation is called monochromatic, from the fact that light constituted by a single oscillation is of a well defined primary color. If the wave is a superposition of different oscillation it is said to have different frequency components, one for each individual oscillation. Such a wave, on the example of light, is called polychromatic.
