What do you mean by Distortionless transmission through a system?

What do you mean by Distortionless transmission through a system?

Advertisements. Transmission is said to be distortion-less if the input and output have identical wave shapes. i.e., in distortion-less transmission, the input x(t) and output y(t) satisfy the condition: y (t) = Kx(t – td)

How a transmission line can be made Distortionless?

Solution: During the transmission of a signal on a transmission line it gets attenuated through attenuation constant(a) which is a function of frequency. The required condition for a distortionless line can be derived from the expression of propagation constant (Y).

What are the types of distortion present on a transmission line?

What are the types of line distortions? The distortions occurring in the transmission line are called waveform distortion or line distortion. Waveform distortion is of two types i.e. frequency distortion and phase or delay distortion.

What is the condition a transmission line should be satisfied to become distortion less line?

The Heaviside condition, named for Oliver Heaviside (1850–1925), is the condition an electrical transmission line must meet in order for there to be no distortion of a transmitted signal.

What is the condition for Distortionless modulation?

Condition for distortionless transmission For distortionless transmission, the amplitude response must be a constant and the phase response must be a linear function of the frequency .

What is lossless transmission line?

A lossless line is defined as a transmission line that has no line resistance and no dielectric loss. This would imply that the conductors act like perfect conductors and the dielectric acts like a perfect dielectric.

What is a lossless transmission line?

What is the value of alpha for lossless line?

0
Answer: a Explanation: For a lossless line, attenuation constant α is 0. Hence substituting α=0 in γ=α+jβ, we get γ= jβ.

What is the type of distortion shown?

Distortion occurs in six main forms: Longitudinal shrinkage. Transverse shrinkage. Angular distortion.

What is waveform distortion in transmission line?

Waveform distortions are common power problems that cause equipment to malfunction and sources of power to overload. It is an unexpected change in the waveforms of current and voltage as they pass through a device.

What is Distortionless line and state the condition for Distortionless line?

Explanation: For a distortionless line, the condition R/L = G/C must be true. On substituting for R = 20, L = 40 mH, C = 40 μF, G = 0.02, we get R/L = 500 and G/C = 500. Thus the line is distortionless.

What is the attenuation constant for Distortionless transmission line?

The attenuation constant of a distortionless line is always zero.
