An audio signal is displayed 8000 times per second. Each sample is represented by 256 different levels. How many bits per second are needed to represent this signal?

## Possible solution

If you have 8000 in binary it would be 1111101000000 but as it is represented in 256 different levels. So, I thought of creating a byte for each digit of 8000. So it would be 8 [00000100] 0 [00000000] 0 [00000000] 0 [00000000] and added everything would be 00000100000000000000000000000000 in binary system.
