RF channel bandwidth

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies . It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth.

This is known as the bandwidth (BW). In this example the bandwidth would be 10 Hz (70 Hz – 60 Hz). You can predict the bandwidth in this case using the simple formula: BW = 2f m where f m is the frequency of the simple sine wave used to modulate with .

Bandwidth is measured in Hertz. A carrier frequency can be modulated using a small frequency component then the range of frequency provided after modulating the signal is generally the bandwidth of the signal. Bandwidth can also be mentioned as the data transfer rate and expressed in bits per second.

The basic difference between the two is that frequency is defined as the rate of radio signal to send and receive communication signals, whereas bandwidth is defined as the difference between the highest and the lowest frequencies of a signal generated .
