wavelength? Wavelength of a sinusoidal wave is the distance between identical points in the adjacent cycles of a waveform signal. Wavelength is commonly designated by the Greek letter lambda (λ)Wavelength is inversely correlated to frequency (figure 1.1)‚ therefore the higher the frequency of the signal‚ the shorter the wavelength. vp Is the phase velocity f is the frequency vp Is the phase velocity f is the frequency λ=vpf Figure 1.1 What is a wave guide?

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 the modulating frequency

I feel so nostalgic a lot of the time‚ watching the waves crashing into shore‚ people paddling out to hit the crests. I remember the feel of the water‚ the road of the wave‚ and the zen like moment when you hit that perfect pipe‚ and ride it halfway back to shore. I’ve been taking in a lot of the local Californian events lately‚ watching the new breed of surfer make their way out to the waves‚ hitting the spots I used to hit‚ part of me feels good‚ part of me misses it. I still hit the ocean when

Windows The Fast Fourier Transform (FFT) is the Fourier Transform of a block of time data points. It represents the frequency composition of the time signal. Figure 2 shows a 10 Hz sine waveform (top) and the FFT of the sine waveform (bottom). A sine wave is composed of one pure tone indicated by the single discrete peak in the FFT with height of 1.0 at 10 Hz. Introduction FFT based measurements are subject to errors from an effect known as leakage. This effect occurs when the FFT is computed from

Surfing as a hobby has really taken off in the UK over the past ten years and with the south-west coast of Cornwall now chock a block with kids all hoping to catch a wave the most adventurous have set their sights on beaches further afield. Biarritz had historically been the surfing capital of Europe ever since Californian author and screenwriter Peter Viertel took to the Bay of Biscay on his board during the filming of his adaptation of Ernest Hemingway’s “The Sun Also Rises “in 1957.

Interference Introduction When two waves of equal intensity combine‚ the intensity of the resulting wave can be anywhere between zero and four times the intensity of the individual waves‚ depending upon the phase difference between them. When they are in phase (the maxima coincide with maxima and the minima coincide with minima)‚ maximum intensity results. When they are exactly out of phase (the maxima of one wave coincide with the minima of the other wave)‚ the result is zero intensity. In

One day my parents got our whole family in our living room and told us that we were all going on a trip to Puerto Vallarta‚ Mexico. Our whole family was so excited so later that night we all went out to eat to celebrate. When we all got home we started getting packed right away. Our plane wasn’t suppose to leave for a couple house but we were all waiting at the airport so that we would not be late. It was about 2:00 pm when our plane took off and It was the start to a long trip. When we finally
