Question

For a given data rate the bandwidth ${\beta }_p$ of a $BPSK$ signal and the bandwidth ${\beta }_o$ of the $OOK$ signal are related as

• A. ${\beta }_p=2{\beta }_0/4$
• B. ${\beta }_p={\beta }_0$
• C. ${\beta }_p=\frac{{\beta }_0}{4}$
• D. ${\beta }_p=2{\beta }_0$.

Answer 1

The correct option is B ${\beta }_p={\beta }_0$

BPSK transmits one bit per symbol, and the symbol rate is 1T, BPSK can transmit 1T bits per second which is same as OOK signal, so ${\beta }_p={\beta }_0$

Hence option B is correct.
