Question 1 Explanation: 
In analog to digital signal conversion following steps are performed: 1. Sampling: The analog signal is sampled every Ts seconds, where Ts is the sample interval or period. The result is a sequence of samples that retains the shape of the analog signal.
2. Quantization: The sampled signal is quantized. The result of sampling is a series of pulses with amplitude values between the maximum and minimum amplitudes of the signal. The set of amplitudes can be infinite with non-integral values between the two limits.
So quantization is the process of mapping a large set of input values to a smaller(countable) set.
3. Encoding: After each sample is quantized and the number of bits per sample is decided. The quantized values are encoded as streams of bits.
