ABSTRACT The manual method of synchronization demands a skilled operator and the method is suitable for no load operation or normal frequency condition. under emergency condition such as lowering of frequency or synchronizing of large machines a very fast action is needed‚ which may not be possible for a human operator. Thus there is a need of autosynchroniser in a power station or in an industrial establishment where generator are employed. This paper describes a microprocessor based set

you get close to metal. It beeps even faster the closer you get to the metal. [pic] Step 6 Why It Works The reason this works is because the loud tone coming from the radio is the calculators electronic circuit producing a radio frequency signal. That being said‚ the radio waves from the calculator reflect off the spoon and are heard on the AM

Change the Repetition block to 1x as the signal will be upsampled in the filter block. c. Run the simulation and observe the frequency domain on spectrum analyzer. Under the Trace Menu‚ select Trace 2 on the spectrum analyzer and press the Clear/Write key. This will allow a comparison between the two signals. What is the approximate null-to-null bandwidth? Are the sidelobe power

for one wavelength to pass (SI Units = seconds) Frequency (f) -> number of cycles that pass by per time interval = Cycles per second = 1 Hertz (Hz) T=(1/f) and f=(1/T) Ex. f=2 Hz = T=.5 seconds Swing? Applied force at a regular interval‚ causes you to go higher‚ high amplitude All object will vibrate of oscillate at a certain frequency called the natural frequency A pendulum (or swing) will swing back and forth at a natural frequency that depends

relationship between the wavelength and frequency of a sine wave. Define fundamental frequency. What is the relationship between a signal’s spectrum and its bandwidth. What is attenuation? Define channel capacity. What key factors affect channel capacity? Problems: Figure 1 shows the frequency domain function for a single square pulse. The signal pulse could represent a digital 1 in a communications system. Note that an infinite number of higher frequencies of decreasing magnitudes is needed

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 echoes depend on how the object

Measure the length of the air column from the surface of the water to open end. 7. Repeat the above steps for the remaining two tuning forks. 8. Record all collected data in tabular (chart or table) format. Calculation: For tuning fork having frequency of 256Hz V = 331.4 + 0.606 X (T) V = 331.4 + 0.606 X (20) V = 343.52 Now‚ V = L F L = 343.52/256 L = 1.34 Ln = (2n-1) x L
