1. An audio signal with a bandwidth of 2.7 KHz is sampled at Nyquist rate and then quantized using a 128-level quantizer. What is the bit rate of the resulting digital signal in Kbps?
2. An audio signal with a bandwidth of 3.9 KHz is sampled at Nyquist rate and then quantized using a 1024-level quantizer. What is the bit rate of the resulting digital signal in Kbps?
3. An audio signal with a bandwidth of 3 KHz is sampled at Nyquist rate and then quantized using a 512-level quantizer. What is the bandwidth of the resulting digital signal in KHz?
4. An audio signal with a bandwidth of 2.8 KHz is sampled at Nyquist rate and then quantized using a 256-level quantizer. What is the bandwidth of the resulting digital signal in KHz?
5. A signal with minimum frequency of 7 KHz is converted to PCM, using the Nyquist rate for sampling and 256 quantization levels. What is the quantization error in SNR(dB)?
6. A signal with minimum frequency of 6 KHz is converted to PCM, using the Nyquist rate for sampling and 512 quantization levels. What is the quantization error in SNR(dB)?
