1

Bandwidth

The range of frequencies produced by the transducer
- how much data can be put through

2

What range of frequencies do wide bandwidth transducers have?

Wide range

3

What is the rule with bandwidths?

That the shorter pulse = the wider bandwidth

4

Why is a wider bandwidth is good?

Offers more flexibility

5

What is the formula for bandwidth?

Max frequency - min frequency

6

What is the formula for operating frequency?

Max f + min f / 2

7

What is the fractional bandwidth formula?

Fractional bandwidth = bandwidth / f x 100%

8

What is the quality factor formula?

Quality factor = f / bandwidth

9

What range of fractional bandwidths do most transducers fall under?

50-100%

10

What happens to the bandwidth when the fractional bandwidth increases?

It increases too

11

What happens to the bandwidth when the quality factor increases?

It decreases

12

Is it better or worse to have a lower quality factor?

Better
- bigger bandwidth
