8. The signal to quantization noise ratio at the output of the quantizer is 52 dB when using quantizer A, and 40 dB when using quantizer B. A. B. C. D. E. F. Quantizer A is 6 bits per sample more than Quantizer B. Quantizer A is 2 bits per sample less than Quantizer B. Quantizer A is 3 bits per sample less than Quantizer B. Quantizer A is 6 bits per sample less than Quantizer B. Quantizer A is 2 bits per sample more than Quantizer B. Quantizer A is 3 bits per sample more than Quantizer B. 9. When we multiply a Polar waveform with a high-frequency sinusoid, we generate: A. QSK modulated signal B. PSK modulated signal C. ASK modulated signal D. FSK modulated signal E. FM modulated signal 10. The following digital carrier modulation techniques can be decoded coherently or non-coherently: A. ASK and QAM B. FSK and QAM C. ASK, FSK D. ASK, QAM and FSK E. QAM and DPSK 8. The signal to quantization noise ratio at the output of the quantizer is 52 dB when using quantizer A, and 40 dB when using quantizer B. A. B. C. D. E. F.
