Question

We want to digitize a human voice. What is the bit rate, assuming 8 bits per sample?

Answer 1

The human voice normally contains frequencies from 0 to 4000 Hz. So the sampling rate and bit rate are calculated as follows: Sampling rate= 4000 X 2 = 8000 samples/s Bit rate = 8000X 8 = 64000 bps = 64 kbps

Answer 2

Digitize human voice and bit rate, assuming that 8 bits per sample are:

• The human voice usually contains waves ranging from 0 to 4000 Hz.

Therefore the sample rate and bit rate is calculated as follows:

• Sample rate = 4000 X 2 = 8000 samples / s.
• Bit rate = 8000X 8 = 64000 bps = 64 kbps .
• Use Delta congestion to compress the next 8 streams -bit whole numbers: 4 6 9 11 13 12 13 14 12 11.
• The human voice usually contains waves ranging from 0 to 4000 Hz. Therefore the sample rate and bit rate are calculated as 4.8 9.

Note:

• We have a low frequency passing signal of 4 kHz.
• If we are sending a match signal, we need a channel with a minimum bandwidth of 4 kHz.
