Difference between spectrum analyzer and distortion analyzer?
The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
Which device use for reduce distortion in sound?
This can be done with an Equalizer. ANSWER: Not an equalizer for sure not unless the distortion is frequency related.
Which class of amplifiers have minimum distortion?
A:class 'a'
What is the meant by harmonic distortion in wave analyzers?
distortion refers to any deviation in any parameter like amplitude,time shape of an electrical signal from an ideal input signal.the distortion occurs due to the inherent non-linear characteristics of the component and devices that form the electronic circuit cause some harmonics to take place in the waveform and resultant deviation is know as harmonic distortion.
Two categories of hazards within a confined space are?
Atmospheric and non-atmospheric
What best reduces atmospheric distortion?
adaptive optics
Are stars pointy?
They only look: 'pointy' due to; atmospheric distortion. Stars are actually a type of 'oblate' spheroid.
Why are stars pointy?

Why are large telescopes built up in remote areas?
Because there is less atmospheric distortion at higher altitudes, and light pollution is avoided.
What is the advantage of the Hubble Space Telescope over a ground based telescope?
One major advantage is that it does not have to contend with the distortion of light caused by the atmosphere.
How do astronomers solve the problems with earth based telescopes?
Adaptive optics which change the shape of large mirrors during observation have helped to reduce atmospheric distortion.
What makes the hubble telescope different from all the land based telescopes you have?
The Hubble telescope is different from land based telescopes in that being in space it does not suffer atmospheric distortion, thus clearer pictures.
What is an advantage of using orbiting telescopes than ground based telescopes?
They are not affected by the diffraction ("twinkling") caused by light travelling through the earth's atmosphere. Also, orbiting telescopes are not affected by atmospheric dust pollution nor light pollution.
What are the problems that can occur with the welding activities and how these can be overcome?
Many problems can be experienced in welding including cracks, infusions and distortion. Generally these can be avoided by eliminating hydrogen, keeping temperature under control and controlling the atmospheric pressure of the environment.
When was Total Distortion created?
Total Distortion was created in 1995.
What is the verb of distortion?
The verb for distortion is distort. As in "to distort something".
When was Copenhagen Distortion created?
Copenhagen Distortion was created in 1998.
