# PCM Codec Issue

Posted on 2008-06-24

Beings of the planet Zamco can hear frequencies up to 30 kHz. However, they can only hear two loudness levelssoft and deafening. The Zamconian telephone system uses PCM codecs. a) How many bits per second will a Zamconian telephone call generate? Do your work in Excel, and copy and paste your results into your answer page. b) How many bytes will it take to store an hour of a Zamconian telephone conversation? (Hint: The answers to a) and b) are 60 bps and 26 MB, respectively.)

Okay I am working on this question for homework for a computer networking class. I am completely puzzled as to what in the world this even means. If anyone can provide any suggestions/resolutions/advice at all -- I would greatly appreciate it!!!

Thank you!
