PCM: Pulse code modulation. It is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, digital telephony and compact discs. The amplitude of this signal is sampled regularly at uniform intervals.
PAM: Pulse amplitude modulation. It is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses.
<span>Lee says, "110, 120, 130, 140, 150."
Lee's starting at 100. Every time she adds 10 pennies she says the number. Since she starts at 100 and then adds the first group of 10, the first number she says is 110. She adds the second group of 10 more pennies to 110 and now she says 120. She does this 5 times to add 5 groups of pennies to the jar. More simply, she needs to count by 10, five times: 110, 120, 130, 140, 150.</span>
