Lectures 2-4:15 Saturday, Sunday, Tuesday and Wednesday. Designed to provide a . working. knowledge of Nonlinear Optics.. Typically, harmonic motion decreases in amplitude with time….this realistic model describes damped harmonic motion.. The damping effect is a result of friction and internal resistance of the system to further motion..

How this topic was chosen and by whom. Why . I am the presenter. Intent . by. D.V.Kamat. Faculty, Department of E&C Engg., MIT . Types of feedback. There are two types of feedback in amplifiers:. Positive feedback(regenerative feedback). Negative feedback(degenerative feedback). Oscillations. © 2014 Pearson Education, Inc.. If an object vibrates or oscillates back and forth over the same path, each cycle taking the same amount of time, the motion is called periodic. The mass and spring system is a useful model for a periodic system. Describe . examples of damped oscillations.. . Need to know. - It is sufficient for students to know that damping involves a force that is always in the opposite direction to the direction of motion of the oscillating particle and that the force is a dissipative force.. .
