There are three types of audiences that can be addressed. The first type is a neutral audience. When addressing a neutral audience it is important to convey facts and inform the audience of background information. In most cases, a neutral audience does not have a lot of knowledge on a specific subject and by giving the audience background information; the presenter can give the audience a complete picture. While the presenter is trying to persuade the reader to agree with their point of view, it is important to represent other views in an impartial manner. If the presenter does not do this, he will leave himself open to criticism. It is important to speak to the audience in a language they can understand. The presenter needs to be sure to appeal to how their views affect the audience on a personal level. When presenting to a neutral audience it is very important not to speak down to them. The presenter should never make the audience feel stupid, if this occurs there is little hope persuading them to agree with the point that is being made. The second type of audience is a friendly audience. Addressing a friendly audience is far easier because the audience is already in agreement with the presenter. It is important to present the friendly audience with information they may have never heard before in the hopes of reinvigorating the audience’s passion for the position on which the presenter and audience already agree. The presenter should stick to the facts and not under mind what the presenter sees as the opposing views weaknesses. The presenter should present new information; this will be beneficial in strengthening the resolve of the friendly audience. The third type of audience is an unfriendly audience. The unfriendly audience is by far the hardest audience to write for. When writing in this situation, it is important to let the audience know the presenter understands their point of view. Finding a common ground is vital; it is paramount for the presenter to show the audience they have empathy and an understanding of their point of view. It is also important to point out what values and beliefs the two arguments have in common.
All of electronics can be divided into two broad categories: analog and digital. One of the most common examples of the difference between analog and digital devices is a clock. On the analog clock, the time is represented by hands that spin around a dial and point to a location on the dial that represents the approximate time. On a digital clock, a numeric display indicates the exact time.
Analog refers to circuits in which quantities such as voltage or current vary at a continuous rate. When you turn the dial of a potentiometer, for example, you change the resistance by a continuously varying rate. The resistance of the potentiometer can be any value between the minimum and maximum allowed by the pot.
If you create a voltage divider by placing a fixed resistor in series with a potentiometer, the voltage at the point between the fixed resistor and the potentiometer increases or decreases smoothly as you turn the knob on the potentiometer.
In digital electronics, quantities are counted rather than measured. There’s an important distinction between counting and measuring. When you count something, you get an exact result. When you measure something, you get an approximate result.
Consider a cake recipe that calls for 2 cups of flour, 1 cup of milk, and 2 eggs. To get 2 cups of flour, you scoop some flour into a 1-cup measuring cup, pour…
