This improvement is for Higher amplitudes only Lower amplitudes only Higher frequency components only Lower frequency components only 2 / 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 3 / 10 Flat top sampling of low pass signals Introducing delay distortion Leads to aliasing Implies oversampling Gives rise to aperture effect 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 Which of the following is a fully digital cordless system? DECT CT1+ CT1 CT0 6 / 10 The process of conversion of data along with its formatting is called: Source Coding Amplifying Formatting Modulation 7 / 10 How many transitions can we make at every bit of time? One Two Three Half 8 / 10 The noise variance for AWGN is: 2N0 N0/4 N0 N0/2 9 / 10 Compression in PCM refers to relative compression of Higher signal frequencies Lower signal frequencies Lower signal amplitudes Higher signal amplitudes 10 / 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 Your score is The average score is 70% 0% Try Again Results : User NameScoreAsdf40%Chetan Vaghela100% Related Posts:VMC (Civil) Online Test SeriesWireless Communication Online Test 6Basics of Civil Engineering Online Test SeriesGSSSB Municipal Engineer Online Test SeriesEcology And Environment Online Test SeriesEnvironmental Engineering Online Test SeriesComputer Networks (GSSSB Sr. Surveyor) Online Test SeriesTRD & Sketching-1 (GSSSB Sr. Surveyor) Online Test SeriesThe Reference Model for Network Communication Test 1GPSSB AAE (Civil) Online Test SeriesWaste Water Technology Online Test SeriesGPSC (Civil) Previous Year Papers Online Test SeriesRTI Act 2005 Online Test SeriesSteel Design (GPSC Civil PYQs) Online Test SeriesDBMS (GSSSB Sr. Surveyor) Online Test SeriesGSSSB Surveyor (Class 3) Full Length Online Test SeriesThe Reference Model for Network Communication Test 2Renewable Sources of Energy Online Test SeriesWireless Communication Online Test 7Water Supply Engineering Online Test SeriesWireless Communication Online Test 3IOT and Applications (GSSSB Sr. Surveyor) Test SeriesSatellite Communication Online Test 1 (Free)Operating Systems (GSSSB Sr. Surveyor) Online Test SeriesDigital Communication Online Test Series
