# Exam Question (Physics)~Help watch

1. Bit rate in B(i) was 114240 bits/s (110000), Frequency is 8.3x108 Hz

Attachment 730546
In case Attachment doesnt work: https://imgur.com/a/1nW3S

I need an understandable explanation please.
2. Frequency can be defined as the number of cycles per second, so I imagine it would need to be greater than or equal to the bit rate in order to be able to keep up.

Coukd you please Explain the second point to me.

Coukd you please Explain the second point to me.
The minimum bandwidth of a channel needs to be equal to the number of bits transmitted per second, i.e. bit rate.
(Bandwidth is the difference between the highest and lowest frequencies of a signal.)
The second point is essentially just reinforcing the answer to the previous question.
