Question

Which signal has a wider bandwidth, a sine wave with a frequency of 100 hz or a sine wave with a frequency of 200 hz?

Answer 1

each signal is a simple signal in this case. The bandwidth of a simple signal
is 0.

so,the bandwidth of both the signals r same.

I hope its helpful.

Answer 2

Answer:

Neither. A wave at a single frequency does not constitute a "bandwidth". Each signal is a simple signal in this case.

Explanation:

Theoretically, a perfect sine wave has zero bandwidth regardless of its frequency. Bandwidth is a measure of a signal's deviation from a perfect sine wave and ability to carry information. A perfect sine wave contains no information at all since it never changes.
