If you press down on a piano key, let's say middle C, it generates a sound wave. Now, imagine that you press it down much harder so that it still plays the same tone but much more loudly. How would pressing the key down harder change the sound wave produced?

amplitude and energy would increase

wavelength and energy would increase

particles in wave move perpendicular to wave

particles in wave move parallel to wave

In some situations, digital cable will produce a much more crisp image than analog. What is one important cause of this?

analog cannot produce crisp images

digital is always better than analog

analog transmits in discrete pulses

digital signals are not affected much by noise

The green plot (top) and red plot (bottom) attempt to transmit the same signal in the graphs. What is the best conclusion that can be drawn? Drag and drop your answer into the box.

the red plot is an a discreet analog signal

the boxlike red plot cannot be useful

the green plot is a discrete analog signal

the red plot is a discrete digital signal

The gray and red lines attempt to transmit the same signal in the graph. What are the best two conclusions that can be drawn?

the gray signal carries more information

the red signal carries more information

Select TWO of the following statements are true about analog signals.

they are transmitted continuously

noise affects them more than digital signals

they are transmitted in discrete pulses

noise affects them less than digital signals

What are TWO major differences between analog and digital signals?

Digital signals are usually clearer than Analog

Analog signals are continuous, Digital are discreet

Analog signals are usually clearer than Digital

Digital signals are continuous, Analog are discreet
