A true pure sinusoid signal lasts forever, from -infinity to +infinity. If it ever turned on or off it would not be a pure single frequency sinusoid signal. Real signals aren't pure.

Why carrier signal are sinusoidal?
It does not have to be. Voltage can be DC, sinusoidal, square wave, triangular wave, etc.
Why cosine wave is used as carrier signal in all modulation techniques. why not sine wave?
The sinusoidal wave is harmonically pure, i.e. it only has one frequency in the frequency domain. If it were not harmonically pure, i.e. if it were not sinusoidal, it would be more difficult, if not impossible, to demodulate it at the receiver.
What is a signal generator for a speedometer?
if the speedometer works off of an input wave (sinusoidal signal) you would think the signal generator would be a source of reference
Why sinusoidal signal is called basic signal?
The sinusoidal signal is called a basic signal because, by Fourier Analysis, you can not further reduce it. It is one sine wave of one frequency of one amplitude of one phase. It has no harmonics. If you converted it from time domain to frequency domain you would only get one line, at the fundamental frequency.
How is sinusoidal signal produced?
You may use a filter which will round off the square pulse to sine wave.The higher order the filter the better the SINE wave . The Square pulse and the sine wave must both be tuned to our required frequency
Is sinusoidal signal be an energy signal?
they have an infinite energy
Why carrier signal are sinusoidal?
It does not have to be. Voltage can be DC, sinusoidal, square wave, triangular wave, etc.
Which type of signal oscillated between maximum and minimum values overtime?
A sinusoidal signal.
Why cosine wave is used as carrier signal in all modulation techniques. why not sine wave?
The sinusoidal wave is harmonically pure, i.e. it only has one frequency in the frequency domain. If it were not harmonically pure, i.e. if it were not sinusoidal, it would be more difficult, if not impossible, to demodulate it at the receiver.
Is there a difference between the Crest and the Peak Dilation of Sinusoidal Signal?
They are the same thing.

What is the wave form of clipping circuit?
As a sinusoidal signal is clipped the waveform approaches a square wave.
What is the duration of Pure as a Lily?
The duration of Pure as a Lily is 1.67 hours.
What is the duration of Pure Luck?
The duration of Pure Luck is 1.6 hours.
What is the duration of Pure Coolness?
The duration of Pure Coolness is 1.58 hours.
