Signal Bandwidth

Signal bandwidth is the range of frequencies used to transmit a signal. It is important in communications, as it determines the rate at which information can be transmitted. If a signal has a higher bandwidth, more data can be transmitted at a faster rate. Signal bandwidth is also important for signal quality; a wider bandwidth can support a higher quality of signal, resulting in higher resolution images or reduced noise in sound signals. Signal bandwidth is used in many applications, including internet networks, radio broadcast systems and digital audio systems.
