QUESTION 1 In Pulse Code Modulation (PCM), what is quantization? a. Quantization describes the sampling of an analog signal using Nyquist's sampling theorem b. Quantization describes the mapping of a single sample to a bit sequence c. If the Nyquist Sampling Theorem s not adhered to, then quantization errors will exist d. None of the above describes quantization QUESTION 2 You want to digitize an analog signal that has a 22kHz bandwidth. According to Nyquist, what should be your sampling rate? a. 11,000 samples per second b. 22,000 samples per second c. 44,000 samples per second d. 22 samples per second QUESTION 3 If you do not apply the Nyquist Sampling Theorem when digitizing an analog signal, what will happen? a. Signal aliasing b. Quantization error c. Increased bit rate error d. All of the above QUESTION 4 You want to digitize a 4000 Hz analog voice grade signal. You select a bit depth of 8 bits per sample. What will be the expected transmitted data rate? a. 4kbps b. 16kbps c. 32kbps d. 64kbps
