Question

What is meant by bandwidth?

Answer 1

1. The distance between the top and the bottom frequencies in a constant frequency range is referred to as a signal's bandwidth.
2. Bandwidth is measured in Hertz and is referred to as passband bandwidth or base bandwidth depending on the context.
3. A signal processing system is effective over a specific frequency range.
4. The response of a system is flat within this frequency range. The frequency response steadily decreases outside of this region.
5. The cutoff frequency is the point in a system's frequency response where the energy flowing through it lowers instead of going through.
6. The difference between the upper and lower cutoff frequencies is known as the passband bandwidth.
7. A baseband bandwidth, on the other hand, is equal to a system's maximum frequency.
8. In many domains, such as electronics, radio communications, digital communications, information theory, and so on, bandwidth in hertz is a crucial notion.
