Find the number of pulses, if the number of quantization levels is 32

1.	Find the number of pulses, if the number of quantization levels is 32 in PCM?(a) 3(b) 6(c) 4(d) 5This question was addressed to me in an international level competition.Question is taken from Methods of Reducing Distortion in section Amplitude Modulation of Analog Communications
Answer» The correct option is (d) 5 Explanation: Quantization is a process in which the continuous range of VALUES of an analog signal is sampled and DIVIDED into non-overlapping (but not necessarily equal) subranges, and a DISCRETE, unique value is assigned to each sub-range. Therefore, number of PULSE in quantisation level =2^n = 32, so n = 5, where n = Quantization Level.
