OUTLINE FOR CHAPTER 2:

SINUSOIDS: THE BASIC SOUND

FUNDAMENTAL CONCEPTS:

1) VIBRATION:

MASS, ELASTICITY, AND A MOMENTARY FORCE
2) FOURIER ANALYSIS

3) THE SINUSOID:

THE TRIGONOMETRY sin a = A/B

THE UNIT CIRCLE

SIMPLE HARMONIC MOTION: AMPLITUDE WITH TIME

 4) PROPERTIES OF A SINUSOID
FREQ. (PERIOD);
AMPLITUDE;
PHASE;
WAVE LENGTH
5) MEASURES OF AMPLITUDE: INSTANTANEOUS; PEAK; ROOT-MEAN-SQUARE 6) A CLASSIC OSCILLATOR A WEIGHT AND A SPRING
