7. Which of the following is not true about non-linear PCM Codes (a) Quantization error is lower for small amplitude analog signal but higher for large amplitude analog signal (b) accuracy is higher for small amplitude analog signal but compromised for high amplitude analog signal (c) the step size is constant (d) the resolution is non-uniform 10.Convert the 8-bit compressed code back to 12 bits PCM Linear Code:11101011. 11.Quantization Involves (a)Sampling the analog signal (b) filtering the analog input (c) converts PAM into finite number of values then converted as binary (d) rounding off the amplitude of the flat top samples 12.for sample rate of 8KHz what is the maximum analog input (in HZ) that will not result to fold-over distortion? Do not include the unit in the final answer. 13.Companding means (a) Compressing the analog signal at the transmitter then expanding at the receiver (b) computing the analog signal at the transmitter then allocation at the receiver (c) Complementing the analog signal at the transmitter and then receding at the receiver (d) complacing the analog signal at the transmitter and at the receiver
