Signal to Noise ratio of a quantizer at the output level is given by: SNR = 1.76 + 6.02 b where b is the number of bits by the quantizer. A speech signal with 4 KHz bandwidth has amplitude varying between +5 and -5V. After sampling the signal it is given as an input to a quantizer. SNR of the quantizer at the output is 49.92 dB. i) What is the maximum quantization error that can occur at this quantizer? ii) What is the quantized value when the sample value is -1.2 using rounding method? iii) What should be the value of quantization level to reduce the quantization noise by a factor of 4?
