Attenuation of low frequencies in reproduction Attenuation of high frequencies in reproduction 3 / 10 The process of conversion of data along with its formatting is called: Source Coding Amplifying Formatting Modulation 4 / 10 The noise variance for AWGN is: 2N0 N0/4 N0 N0/2 5 / 10 How many transitions can we make at every bit of time? One Two Three Half 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 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 9 / 10 Compression in PCM refers to relative compression of Higher signal frequencies Lower signal frequencies Lower signal amplitudes Higher signal amplitudes 10 / 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 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.)
