What is the period of Sinx?
360 degreesIt is usually measured in the x-axis units, such as degrees.
The period for y=sinx is 360 degrees because greater values than 360 is when the graph starts to repeat itself over again..
What is a power signal?
If the signal energy over one period is larger than zero but finite, then the total energy is infinite and the signal power is finite. Therefore, the signal is a power signal. If the signal energy in one period is infinite, then both the power and the total energy are infinite.
What is DFT and its properties?
DFT shifting property states that, for a periodic sequence with periodicity i.e. , an integer, an offset. in sequence manifests itself as a phase shift in the frequency domain. In other words, if we decide to sample x(n) starting at n equal to some integer K, as opposed to n = 0, the DFT of those time shifted samples.

What is frequency shifting property?
Modulation / Frequency Shifting property of the Fourier Transform. Modulation means multiplying a signal with a complex exponential. In the Fourier Transform, modulating a signal in time domain corresponds to shifting it in the frequency domain.
When a continuous signal is a mixture of two continuous periodic signals what is its periodicity?
Explanation: When a continuous signal is a mixture of two continuous periodic signals if their time periods are T1 and T2, and their ratio is rational number, then, the periodicity of the continuous time signal will be the LCM of T1 and T2.
What is the fundamental period?
The fundamental period of a function is the period of the function which are of the form, f(x+k)=f(x) f(x+k)=f(x), then k is called the period of the function and the function f is called a periodic function.
Is Sin 3 2t periodic?
by simply matching these to i.e. π = 3π/3 = π , we get fundamental period of sin^3(2t), which is π.
What are the two types of Fourier series?
Explanation: The two types of Fourier series are- Trigonometric and exponential.
What is periodic signals with examples?
Examples of periodic signals include the sinusoidal signals and periodically repeated non-sinusoidal signals, such as the rectangular pulse sequences used in radar. Non-periodic signals include speech waveforms and random signals arising from unpredictable disturbances of all kinds.
How do you find the fundamental period?
The minimum value of T that satisfies x(t) = x(t + T) is called the fundamental period of the signal and we denote it as T0. Examples of periodic signals are infinite sine and cosine waves. Examples: Given x1(t) = cos(3t), and x2(t) = sin(5t).
What is natural time period?
A. Natural Period. Natural Period Tn of a building is the time taken by it to undergo one complete cycle of oscillation. It is an inherent property of a building controlled by its mass m and stiffness k. These three quantities are related by its units are seconds (s).
What is the difference between signals and information?
What is the difference between signals and information? … Signal is the actual entity that is transmitted from transmitter to receiver while the information is the content of the message signal or we can say knowledge that is communicated by the message signal.
What is the time period of a periodic signal in actual terms?
3. What is the time period of a periodic signal in actual terms? Explanation: The periodic signals have actually a time period between t=-∞ and at t= + ∞. These signals have an infinite time period, that is periodic signals are actually continued forever.
What is an even signal?
A signal is referred to as an even if it is identical to its time-reversed counterparts; x(t) = x(-t). Odd Signal: A signal is odd if x(t) = -x(-t). An odd signal must be 0 at t=0, in other words, odd signal passes. the origin.
What is the formula of Fourier transform?
Plancherel’s formula is Parseval’s formula with g = f. This says a function and its Fourier transform have the same L2 form for definitions F+τ1, F-τ1, F+1τ, and F-1τ. For definitions F+11 and F-11 the norm of the Fourier transforms is larger by a factor of √2π.
