This improvement is for Higher amplitudes only Lower amplitudes only Higher frequency components only Lower frequency components only 2 / 10 The line code that has zero dc component for pulse transmission of random binary data is Non-return to zero (NRZ) Alternate mark inversion (AMI) Return to zero (RZ) None of the above 3 / 10 How many transitions can we make at every bit of time? One Two Three Half 4 / 10 Increased pulse width in the flat top sampling, leads to No harmful effects in reproduction Greater aliasing errors in reproduction. Attenuation of low frequencies in reproduction Attenuation of high frequencies in reproduction 5 / 10 Compression in PCM refers to relative compression of Higher signal frequencies Lower signal frequencies Lower signal amplitudes Higher signal amplitudes 6 / 10 Flat top sampling of low pass signals Introducing delay distortion Leads to aliasing Implies oversampling Gives rise to aperture effect 7 / 10 Which of the following is a fully digital cordless system? DECT CT1+ CT1 CT0 8 / 10 The noise variance for AWGN is: 2N0 N0/4 N0 N0/2 9 / 10 The process of conversion of data along with its formatting is called: Source Coding Amplifying Formatting Modulation 10 / 10 In delta modulation, the slope overload distortion can be reduced by Increasing the step size Decreasing the sampling rate Decreasing the granular noise Decreasing the step size Your score is The average score is 70% 0% Try Again Results : User NameScoreAsdf40%Chetan Vaghela100% Related Posts:Applications of GIS in Civil Engineering Test SeriesAMC Assistant Technical Supervisor (Eng.)
