Question 17 A low-pass signal with a bandwidth of 400 KHz is sampled at Nyquist sampling rate using 512 levels of quantization. The SNR (dB) of the output signal is a. 50dB b. 76dB C 35dB d. 51.2dB A Moving to the next question prevents changes to this answer Question 20 A low-pass signal with a bandwidth of 400 KHZ is sampled at Nyaulist sampling rate using 256 levels of quantization. The bandwidth of the PCM signals is a. 2.4 MHE b. 256 MHZ c. 400 Mbps Question 21 Aline has a signal-to-naise ratio of 30de and a bandwidth of 4000 Hz. The the maximum data rate supported by this line is approximately equals to a. 10 kpbs b. 20 kpbs c. 40 Kbps d. 12 Kbps Question 25 of 25 Question 25 1 points The bipolar-AMI waveform representing the binary sequence 0100101011 is transmitted over a noisy channel. The received waveform is shown in Figure below, it contains a single error. Locate the position of this error. HU
