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.

Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
Can dc to ac converter burn up power tools?
They can. Low end inverters often use a square wave output, instead of a sine wave output. This causes harmonic distortion that can sometimes damage equipment. One of the damage mechanisms is the simple rectifier - when the diode conducts and recharges the filter capacitor in a power supply, if the slope of the step change is vertical, as it would be with a square wave, the instantaneous current through the diode and capacitor tries to be infinite, and that can damage the diode or capacitor.
Which harmonics is suppressed by the front end filter of a distortion factor meter?
fundamental wave component is filtered in the front end.
Why signal distorted after amplification?
Distortion can be caused by many things, and varying levels. Two of the most common are;- Clipping. This is when the amplifier has reached maximum or minimum amplification and causes the wave form, to be flat top and bottom. It squares the waveform and sounds rough. Usually due to the input signal being too high. Harmonic. This is a form of feedback, where the input is receiving signal from the output. Sometimes the amplifier 'rings' at a harmonic of the input and is re-amplified giving a tinny, squeaky, sound. Caused by bad screening or component layout.
What is amplitude distortion?
Amplitude distortion occurs in an electronic signal when the power of the amplifier is not great enough to carry the sine wave to its intended peak amplification. If you look at the wave form of a amplitude distorted output signal, it would look like someone had neatly sliced off the top of a hill. Though amplitude distortion is usually an undesired result, the effect is sometimes used intentionally for audio applications, such as a distorted rock guitar which gives that crunchy rock sound.
What is a distortion analyzer?
A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave. For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave. If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present. The analyzer does this by supplying a low distortion sine wave test signal which is connected to the device under test. The output from the device is connected to the input of the analyzer where the original input signal is filter out with a precision notch filter. Anything left over after filtering represents distortion components and noise. Amplifiers will frequently have a "Total Harmonic Distortion plus Noise" specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments. Other notable manufacturers are Sound Technology Corporation and Textronix.
What is the need of wave shaping?
Wave shaping is needed to modify the shape of a waveform to achieve desired characteristics such as distortion, timbre, or harmonic content. It is commonly used in audio signal processing to create unique and interesting sounds in music production and synthesis.
What is the fifth harmonic of a 500 Hz triangular wave?
The fifth harmonic of a 500 Hz triangular wave would be at a frequency of 2500 Hz. This means that the fifth harmonic would have a frequency that is five times the fundamental frequency of the triangular wave.
A source that is vibrating with simple harmonic motion produces a?
A source vibrating with simple harmonic motion produces a sinusoidal wave.
How does a half wave rectified sine wave sound like?
It's hard to define a sound, but here's a try: A half-wave rectified sine sounds harsh and whiney. Not as sharp and jagged as a square wave, but not nearly as pure and smooth as a sine. The key is to realize that the half-wave rectified sine is a sine plus a significant load of harmonics, and wherever there is a lot of harmonic energy, we call it "total harmonic distortion". So the bottom line is, anything that isn't a pure sine, you would say it sounds "distorted".
What are the properties of a harmonic wave and how does it differ from other types of waves?
A harmonic wave is a type of wave that has a regular, repeating pattern of oscillation. It is characterized by having a constant frequency and wavelength. Unlike other types of waves, such as non-harmonic or irregular waves, harmonic waves have a well-defined and predictable pattern of motion.
Can solve the harmonic oscillator expectation value?
The expectation value of an operator in the harmonic oscillator can be calculated by using the wave functions (eigenfunctions) of the harmonic oscillator and the corresponding eigenvalues (energies). The expectation value of an operator A is given by the integral of the product of the wave function and the operator applied to the wave function, squared, integrated over all space.
Describe the effects of complex waveforms on electrical systems?
Because a complex wave is purveyed as a 'distortion', this generally equates to an effect on what output the circuit gives. As the complex wave is, as quoted, the sum of the fundamental and the 3rd harmonic (commonly known as superposition), the nature of the effect on electrical and electronic systems are determined by how distorted the complex waveform is.
What is distortion in analog electronics?
If you feed a sine wave through an amplifier that isn't exactly linear, the output will be distorted, not a pure sine wave. Distortion is the defect where the output from a device does not mirror the input.
What is third harmonic?
The third harmonic is a frequency that is three times the fundamental frequency of a wave or signal. It is a multiple of the fundamental frequency and is characterized by having three times the wavelength and three times the frequency of the original wave.
What are the properties and significance of wave functions of harmonic oscillator in quantum mechanics?
The wave functions of a harmonic oscillator in quantum mechanics describe the probability distribution of finding a particle at different positions and energies. These wave functions are characterized by specific properties, such as being oscillatory and symmetric. The significance of these wave functions lies in their ability to accurately predict the behavior of particles in harmonic oscillator systems, providing valuable insights into the quantum nature of physical systems.
What vibration of the wave is defined as that which has the lowest frequency?
The vibration of the wave with the lowest frequency is the fundamental vibration. It is also known as the first harmonic and typically has the longest wavelength in the wave.
