Attenuation of low frequencies in reproduction Attenuation of high frequencies in reproduction 5 / 10 How many transitions can we make at every bit of time? One Two Three Half 6 / 10 Compression in PCM refers to relative compression of Higher signal frequencies Lower signal frequencies Lower signal amplitudes Higher signal amplitudes 7 / 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 8 / 10 Companding in PCM systems lead to improved signal to quantization noise ratio. This improvement is for Higher amplitudes only Lower amplitudes only Higher frequency components only Lower frequency components only 9 / 10 Which of the following is a fully digital cordless system? DECT CT1+ CT1 CT0 10 / 10 The process of conversion of data along with its formatting is called: Source Coding Amplifying Formatting Modulation Your score is The average score is 70% 0% Try Again Results : User NameScoreAsdf40%Chetan Vaghela100% Related Posts:Wireless Communication Online Test SeriesAdvance Surveying (GSSSB Sr. Surveyor) Online Test SeriesGSSSB Senior Surveyor (Class 3) Full Length Test SeriesWireless Communication Online Test 2Wireless Communication Online Test 5Building Materials Online Test SeriesWireless Communication Online Test 7Satellite Communication Online Test 1Strength of Materials Online Test SeriesRCC Design Online Test SeriesGSSSB Senior Surveyor Online Test SeriesConcrete Technology Online Test SeriesBridge Engineering (GPSC Civil PYQs) Online Test SeriesGSSSB Surveyor (Class 3) Full Length Online Test SeriesThe Reference Model for Network Communication Test 2Computer Networks (GSSSB Sr. Surveyor) Online Test SeriesGPCB (AEE) Online Test SeriesCivil Engineering Online Test SeriesWindows Programming Online Test SeriesPreparation And Study of Maps Online Test SeriesTRD & Sketching-1 (GSSSB Sr. Surveyor) Online Test SeriesGPSC (Civil) PYQs Online Test SeriesEnvironmental Engineering Online Test SeriesSolid Mechanics (GPSC Civil PYQs) Online Test SeriesBuilding Construction Online Test Series
