Question: 1 / 400

When discussing signal transmission, what does 'bandwidth' refer to?

The maximum amplitude a signal can reach

The number of bits per second transmitted

The range of frequencies that can be transmitted by a channel

Bandwidth refers to the range of frequencies that can be transmitted by a channel. It is a crucial concept in signal transmission as it determines the amount of data that can be sent over a communication medium within a given time frame. In practical terms, bandwidth indicates the difference between the highest and lowest frequency signals that a channel can effectively carry, which impacts the speed and quality of the data transmission.

When a channel has a wider bandwidth, it can transmit a greater variety of frequencies, allowing for the transmission of more data or higher quality signals. For instance, in telecommunications and networking, a higher bandwidth typically results in faster data rates. Consequently, understanding bandwidth is essential for engineers when designing systems for effective communication and data transfer.
