The attenuation constant causes phase distortion and the phase constant causes frequency distortion. State True/False.

Correct Answer: False
There are always some distortions, even in the perfect transmission line. This is due to the variation of the secondary parameters. The attenuation constant causes the frequency distortion, whereas the phase constant causes the phase distortion.

The distortionless line is one in which the attenuation constant and phase constant are independent of the frequency. State true/false.

If the attenuation due to dielectric loss and attenuation due to conductor loss in a microstrip transmission line is 0.024Np/m and 0.0724 Np/m, then the unloaded quality factor if the propagation constant is 151 is:

What is the total harmonic distortion if the amplitude of first harmonic distortion is 20dB and second harmonic distortion 25dB?

What is the total harmonic distortion if the amplitude of first harmonic distortion is 20dB, second harmonic distortion 25dB and external noise is 10dB?

If propagation constant is 12:60°, then the value of phase constant and attenuation constant is:

The length of a ferrite slab required operating with a minimum forward insertion loss and 30 dB reverse attenuation and the reverse attenuation at this point is:

An audio signal (say from 50 Hz to 10000 Hz) is frequency translated by a carrier having a frequency of 106 Hz. The values of initial (without frequency translation) and final (after frequency translation) fractional change in frequency from one band edge to the other are

The frequency response of the filter in the stop band. i. Decreases with increase in frequency ii. Increase with increase in frequency iii. Decreases with decrease in frequency iv. Increases with decrease in frequency

The propagation constant of a wave with attenuation and phase constant given by 2 and 3 respectively is

Determine the attenuation per kilometer for a fiber whose length is 2 km, output voltage is 2.1 V at a wavelength of 0.85μm. The output voltage increases to 10.7 V when the fiber is cut-back to leave 2 metres. Determine the attenuation per km for the fiber at wavelength 0.85μm.
