Question

Typical T1 voice lines have 24 channels with each capable of carrying 1 telephone conversation with "8-bit" quantization and 8,000 samples/second. If we apply this to storing a voice clip on disk, how much storage (in bits) does a 10 second clip take. 64,000 bits 640,000 bits 6,400,000 64.000.000 bits

Answer 1

B. 640,000 bits

Step-by-step explanation:

From the given question,

The voice line has 24 channels with each having the capacity for 1 telephone conversation with the size of 8 bits and 8, 000 samples/second.

Thus for a 10 seconds clip, the rate = 8 000 × 10

= 80 000

The rate is 80 000 samples/second.

The size of the storage in bits = rate ×8 bits

= 80 000 × 8

= 640 000 bits

Therefore, the size of the storage required for storing the video clip on disk is 640 000 bits.
