1.	Find the number of pulses, if the number of level is 128 in PCM?(a) 3(b) 6(c) 4(d) 7The question was posed to me by my college director while I was bunking the class.The above asked question is from Power Calculation topic in chapter Amplitude Modulation of Analog Communications
Answer» RIGHT choice is (d) 7 Best explanation: A PULSE in signal PROCESSING is a rapid, transient change in the amplitude of a signal from a baseline VALUE to a HIGHER or lower value, followed by a rapid return to the baseline value. Therefore, 2^n = 128, so n = 7.
