Final answer:
To route signals to their desired outputs in a functional sound system, use a signal generator and an oscilloscope to produce and analyze sound.
Step-by-step explanation:
In order to route signals to their desired outputs in a functional sound system, you can use a signal generator and an oscilloscope. Connect the function generator to a speaker to produce sounds of different frequencies and amplitudes, and use a microphone connected to the oscilloscope to display the characteristics of the sound produced. The oscilloscope picks up the electrical signal converted from the sound by the microphone.
It is important to properly connect the speakers in stereo systems by following the color-coded terminals. If the wires are reversed, the speaker will move in the opposite direction. This is because when the electrical signal is sent through the wires in opposite directions, the speakers will produce sound waves that interfere with each other, resulting in cancellation instead of reinforcement of the sound waves.
