Crossover distortion is a type of distortion which is caused by switching between devices driving a load, most often when the devices are matched. It is most commonly seen in complementary, or "push-pull", Class-B amplifier stages, although it is occasionally seen in other types of circuits as well.

What is signal distortion in transmission lines?
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
Auto correlation and cross correlation?
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
What type of fading cause serious distortion of modulating signal?
selective fading
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
Unit step signal is energy or power signal?
The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.
What is meant by zero phase frequency how it affects the signal?
Zero phase frequency refers to the frequency at which the phase shift of a signal is zero, meaning that the output signal is in perfect alignment with the input signal. This concept is crucial in signal processing, particularly in filtering, as it ensures that the signal's timing and amplitude remain intact. When a signal is processed at zero phase frequency, there is no distortion or delay introduced, preserving the signal's integrity. Deviations from this frequency can introduce phase shifts that alter the timing and shape of the signal, potentially leading to unwanted effects.
What most measure used to measure distortion?
The Total Harmonic Distortion (THD) is commonly used to measure distortion in audio equipment. It quantifies the amount of harmonic distortion present in a signal compared to the original signal. Lower THD values indicate less distortion in the audio signal.
What is the effect of adding a delay before or after distortion in a signal chain?
Adding a delay before distortion in a signal chain can create a more pronounced and defined distortion effect, while adding a delay after distortion can create a more spacious and atmospheric sound.
What is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
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.
What is distortion criteria?
Distortion criteria refer to the acceptable level of distortion or error in a signal or system before it is considered unacceptable. It helps in evaluating the quality of the output signal by comparing it to the original input signal. Various measurements and standards are used to determine distortion criteria in different contexts such as audio processing, image processing, and data transmission.
How to improve harmonic distortion?
To reduce harmonic distortion, you can use higher quality components in your audio equipment, ensure proper grounding and shielding to minimize interference, and use digital signal processing tools to correct any distortion in the signal. Additionally, keeping signal levels within the optimal range and avoiding overloading the equipment can also help reduce harmonic distortion.
What is signal distortion in transmission lines?

What is Attenuation distortion in networking?
Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency response across the bandwidth of the medium.
What does distortion factor describe?
The distortion factor is a measure of how much a signal deviates from its original form after passing through a system or device. It indicates the level of unwanted changes or alterations to the signal, such as noise, harmonics, or frequency shifts, which can affect the quality and fidelity of the signal. A lower distortion factor value indicates that the signal remains closer to its original form and is less affected by unwanted modifications.
How distortion is measured by a distortion meter?
A distortion meter measures audio signal distortion by comparing the output of an audio device to its input. It typically analyzes the waveform of the signal and calculates the percentage of distortion, which can include harmonic distortion and intermodulation distortion. By using fast Fourier transform (FFT) techniques, the meter identifies and quantifies unwanted frequency components introduced by the device under test. The results help assess the fidelity and performance of audio equipment.
How can you use the word distortion in a sentence?
(A distortion is an alteration, faulty image, or inaccurate representation.)"Distortion of facts is an example of unethical journalism.""A distortion in the radio signal made the messages unintelligible.""A curved mirror will often produce a humorous distortion in your reflection."
