Question

How do I calculate bandwidth frequency?


Open in App
Solution

Definition of Frequency:

The whole number of cycles of the waveform found in the second-to-one cycle of a wave is counted as its frequency. It essentially represents the frequency of complete wave cycles occurring in a unit of time as a whole. Two different waveforms are shown in the figure below:

Definition of Bandwidth:

Frequency and bandwidth are closely related, yet bandwidth is indisputably not frequency. But frequency spectrum refers to bandwidth. The difference between the upper and lower frequency components of a signal is known as bandwidth. This is how the amount of data delivered per second is specified.

The portion of the frequency spectrum that has most of the signal energy is called the essential bandwidth. Fractional bandwidth is calculated by dividing the bandwidth of the device by the central frequency.

  1. The difference between high and low frequencies in a continuous frequency range is known as bandwidth. Typically measured in hertz, it can specifically refer to baseband bandwidth or passband bandwidth, depending on the situation.
  2. It is described as the number of recurring events that occur each unit of time. The number of waves passing a fixed place in a unit of time.
  3. In other words, bandwidth is the difference between lower and higher frequencies.
  4. The difference between a signal's upper and lower frequencies is referred to as its bandwidth. The signal's bandwidth (B) is equal to the difference between the higher or upper frequency.

Difference Between Frequency and Bandwidth:

  1. The two major concepts regarding data transmission are frequency and bandwidth. The main difference between frequency and bandwidth is that the former represents the number of complete cycles that occur in a given period. In contrast to bandwidth, the total amount of data transmitted over a given period of time.
  2. Frequency and bandwidth both have the same unit of measurement, i.e. Hertz. But both have different meanings when studied in the context of networking. In this article, we will see how bandwidth differs from frequency.
