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
