I am not sure I completely understand your question.
Each string is tuned to a wavelength that represents a sound wave, The strings are the oscillators. They move back and forth to create compressions and decompression within the air which your ear interprets as a sound.
~MECHASUN~
Yes. Each string is tuned to a different note of the scale.
Tighten (or loosen) the strings. There is a pedal that releases the dampening pads.
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
Feedback oscillators have a closed loop gain of
