## Bandwidth

### www.3dic.org/Bandwidth

Bandwidth is a measure of the width of a range of frequencies (measured in hertz or GHz) or the bit rate of available or transfered data (measured in bits per second or Gbps).

### Bandwidth (Frequency)

- In analog systems, bandwidth is the difference between the upper and lower frequencies in a continuous set of frequencies.
- In signal integrity analysis, the bandwidth are the most significant sine-wave frequency components associated with a signal (bandwidth determined by rise time), a measurement, a model, or an interconnect.

### Bandwidth (Bit rate)

- In digital systems, bandwidth is the bit rate of available or consumed information capacity expressed typically in metric multiples of bits per second.

- For instance, the Wi-Fi standard IEEE 802.11ad operates in the 60 GHz (V band) spectrum with a bandwidth of 2.16 GHz to achieve data transfer rates of 7 Gbps.
