How many bits of data will be produced if voice is converted, Computer Engineering

Assignment Help:

If voice is converted to digital form using PCM, how many bits of data will be produced in half a second?

While voice is converted to digital by using PCM that is Pulse Code Modulation a device termed as codec (coder/decoder) is used producing an eight bit number. The codec creates 8000 samples per second. Out of eight bits 7 bits are for data and 1 bit is for control.

Therefore data produced per second will be 7*8000=56000 bits per second and 56000/2 = 28000 bits in half a second.
