It occurs mainly due to incorrect biasing and clipping. Ans. To minimize the substantial distortion due to bit-shifting, Xuan et al. In this region, I c =βI b where Ic is collector current and Ib is base current, following linear relation y=mx. which will improve your skill. Amplitude Distortion: This type of distortion occurs due to attenuation in the peak value of the waveform. C. Total amount of distortion D. Total amount of amplitude distortion Answer: A Clarification: THD (Total Harmonic Distortion) is a measurement of the harmonic distortion present in a signal. Amplitude distortion is distortion occurring in a system, subsystem, or device when the output amplitude is not a linear function of the input amplitude under specified conditions.. Generally, output is a linear function of input only for a fixed portion of the transfer characteristics. The shift in “Q point” and amplification for less than 360⁰ of the input signal leads to amplitude distortion. Answer: (c) reading errors due to inclined observation are eliminated by removing parallax between the pointer and its image in the mirror. It is the signal distortion caused due to the overlapping of adjacent spectrums of a sampled signal if the sampling frequency is less than the Nyquist rate.

Feb 18,2021 - Torsion - MCQ Test 1 | 20 Questions MCQ Test has questions of Mechanical Engineering preparation. Which phenomenon occurs due to an increase in the channel bandwidth during the transmission of narrow pulses in order to avoid any intervention of signal distortion? Amplitude Distortion due to Incorrect Biasing If the transistors biasing point is correct, the output waveform should have the same shape as that of the input waveform only bigger, (amplified). 3. Compression in time domain b. In amplitude modulation, it is particularly important that the peak value of the modulating signal be less than the peak value of the carrier. Explanation: Distortion occurs when the modulating signal amplitude is greater than the amplitude of the carrier, causing incorrect information to be transmitted. Why is the PAM signal contaminated by noise? Due to the additive noise, the shape of the PAM signal will get modified. Q.28. Feb 17,2021 - Amplitude Modulation | 10 Questions MCQ Test has questions of Electronics and Communication Engineering (ECE) preparation. 8. In amplitude modulation, it is particularly important that the peak value of the modulating signal be less than the peak value of the carrier. It is the ratio of sum of power of all harmonic components to the power of the fundamental frequency of the signal. (c) reading errors due to inclined observation are eliminated by removing parallax between the pointer and its image in the mirror (d) any of the above. a. Clarification: Distortion occurs when the modulating signal amplitude is greater than the amplitude of the carrier, causing incorrect information to be transmitted.
