Telecommunications Tutorial ‐ Part 2 Available to Purchase

As explained in Part 1, digitisation brings with it numerous benefits although digitised speech of good quality requires a bit rate of 64 kbps, which implies that a channel of 32 kHz will be required (see Part 1, page 61). The same speech in analogue form could be accommodated within a frequency band of 5 kHz, so digitisation requires more bandwidth.
