which different frequencies are analyzed with different resolutions. A wave is an oscillating function of time or space and is periodic. In contrast‚ wavelets are localized waves. They have their energy concentrated in time or space and are suited to analysis of transient signals. While Fourier Transform and STFT use waves to analyze signals‚ the Wavelet Transform uses wavelets of finite energy.

people don’t question the things that are obvious to us. The things we see‚ how do we see it? What makes it visible to us? Is it only because we have eyes‚ or is there another factor.

Another question we could ask from our daily life is that how come we can hear? What is it that we hear? Why do we hear it and deaf people don’t? How do we receive any sound? People

Radio waves for Communication Radio waves are electromagnetic waves with wavelengths larger than the infrared light. Like all other electromagnetic waves‚ they travel at the speed of light. The wavelengths can vary from the size of a football field to the size of a football. They can be produced naturally by large stars and by lightning. Man-made radio waves are used for transmitting signals and currents. Specific Properties of Radio Frequency (RF) Current Radio frequency is the frequency of radio

Namee: Paul G. Zamora (Homework in Performance Techniques) Sound Waves- A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air‚ water‚ or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration‚ such as a ringing telephone‚ or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them
