The temperature of a particular place varies between 14°C and 34°C. For the purpose of transmitting the temperature record of that place using PCM the record is sampled at an appropriate sampling rate and the samples are quantized. If the error in the representation of the samples due to quantization is not to exceed ± 1% of the dynamic range, the minimum number of quantization levels that can be used will be

1.	The temperature of a particular place varies between 14°C and 34°C. For the purpose of transmitting the temperature record of that place using PCM the record is sampled at an appropriate sampling rate and the samples are quantized. If the error in the representation of the samples due to quantization is not to exceed ± 1% of the dynamic range, the minimum number of quantization levels that can be used will be
