baud rate generator is a frequency divider

Basically the baud rate can never be greater than the bit rate. Baud rate can only be equal or less than the bit rate. However, there are instances that baud rate maybe greater than the bit rate. In Return-to-zero or Manchester encoding, where there are two signaling elements, the baud rate is twice the bit rate and therefore requires more bandwidth.

baud rate = symbol rate= modulation rate

all the same thing

whats the baud rate of the modem of the computer

It is impossible to answer that question.

On the other hand if you assume this:

- Baud rate = symbol rate

- Bit rate = bits per second

The following formula is valid:

Baud rate = bit rate / 10

If 1024 QAM is used.
