... of digital transmission. 4. 23 We want to digitize the human voice. What is the bit rate, assuming 8 bits per sample? Solution The human voice normally contains frequencies from 0 to 40 00 ... errors.  BUT, the more zones the more bits required to encode the samples  higher bit rate Chapter 4: Digital communications Lecturer: M.Eng.
