Answer #1

C. Pulse code modulation (PCM) is the original technique used to digitize voice with 8 bits of sampling 8,000 times per second, which yields 64Kbps for one voice channel. Answer A is incorrect because DAT is digital audio tape and is an analog voice-transmission method. Answers B and D are incorrect because CDMA and GSM are methods for cellular phone transmission.
