Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Use the standard bandwidth of co-axial cable.
A co-axial cable has an approximate bandwidth of
\[ 750\ \text{MHz} \]
Step 2: Use bandwidth required for one TV signal.
One TV signal requires approximately
\[ 6\ \text{MHz} \]
Step 3: Find the maximum number of TV signals.
\[ \text{Number of TV signals} = \frac{\text{Total bandwidth}}{\text{Bandwidth per TV signal}} \]
\[ =\frac{750}{6} \]
\[ =125 \]
Step 4: Final conclusion.
Hence, the maximum number of TV signals that can be transmitted is
\[ \boxed{125} \]
