1.	What does DPCM stand for?(a) differential pulse code modulation(b) data pulse code modulation(c) dynamic pulse code machine(d) dynamic pulse code modulationThis question was addressed to me in semester exam.I would like to ask this question from Codecs topic in division Interfacing to the Analog World of Embedded Systems
Answer» Right answer is (a) differential pulse CODE MODULATION Easiest explanation: The differential pulse code modulation is similar to pulse code modulation, but DPCM uses an encoded value which is the DIFFERENCE between the CURRENT and the previous sample.
