In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

Doppler Effect Objectives * Measure the detector frequency for waves emitted from a slowly moving source as that source is approaching the detector. (Exploration 1) * Calculate the detector frequency for waves emitted from a slowly moving source as that source is moving away from the detector. (Exploration 2) * Sketch the wave-front patterns for wave sources with various source speeds. (Exploration 3) Description of Activity In this activity‚ you will study waves that travel from

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected‚ absorbed‚ and also filtered by our different body parts. It’s then collected by our pinnae (the external part of or ears)‚ whose dimensions further affect the sound on its way into ear. There‚ vibrations are translated into signals‚ which are interpreted by your brain. In the 1930s‚ two scientists at Bell Labs‚ Harvey Fletcher and Wilden A. Munson

Ultrasound Ultrasound is an imaging technique that uses high frequency sound wave and echoes. There are different kinds of ultrasound they are two-dimensional image‚ 3D ultrasound imagining‚ and Doppler ultrasound. Doppler ultrasound is based on the Doppler effect. (Doppler effect is whenever relative motion exists between a source of sound and a listener and the frequency of the sound heard by the listener sounds different compared to the frequency when there is no motion.) The frequency of the

CHAPTER 1 INTRODUCTION 1.1 Background Design of Experiment (DOE) was developed in early 1920’s by Sir Ronald Fisher at the Rothamsted Agriculture Field Research Station in London‚ England. DOE can be used to observe how the design factor or parameters affect the performances. DOE also used to planning‚ designing and analyzing the experiment so that the objectives can be achieved and obtain effective results. The use of DOE in experiment reduce the time and effort with the availability of modern simulation
