following components. An antenna is used to convert electro-magnetic waves into electrical oscillations. Amplifiers are used throughout the receiver to boost signal power at radio‚ baseband and intermediate frequencies. The core of the FM receiver‚ the discriminator‚ comes in various circuit forms and is used in detection and demodulation. Basically‚ its role is to extract the intelligence or message from the carrier wave. Another component‚ essential in most electronic circuits‚ is the power

Task 1: COMMUNICATION Radio waves that pass through the same place at the same time cause interference. Constructive interference occurs when two waves combine to have greater amplitude than either of the component waves. A radio transmitter sends out two signals‚ one for voice communication and another for data. Suppose the equation of the voice wave is v = 10 sin(2t 30˚) and the equation of the data wave is d = 10 cos(2t + 60˚). a. Draw a graph of the waves with the use of a program or software when they are

By this‚ it means that Korean fashion‚ music‚ dances‚ language‚ businesses‚ etc. are all included. On the other hand‚ the former only includes the Korean music. K-pop is actually the abbreviated form of Korean Popular Music. So this makes K-pop only a part of the Korean Wave in the Philippines. K-pop or the Korean Popular Music is specifically

November 5th) Concept Check 14.4 2. List the major differences between P‚ S‚ and surface waves. P & S waves travel within material while Surface waves occur on the outer surface of a material. Concept Check 14.5 1. What information does a travel-time graph provide? A Travel Time graph plot the different arrival time of each wave (P wave‚ S Wave). This allows us to measure distance in relation to the time each wave took to arrive‚ and give us the distance of the epicenter of an earthquake. 2. Briefly

Tsunami A tsunami is a high-speed sea wave of seismic origin created by "an underwater earthquake‚ landslide‚ or volcanic eruption"(Johnston‚ 2001). A shallow water wave is a water wave in which the wavelength is larger than the water height‚ or ocean depth (Banks‚ 1998). Since humans are concerned with a tsunami primarily at the shore‚ where the water is not deep‚ tsunami are explored as a shallow water wave. That is‚ people are most concerned with the height of a wave as it hits shore. Tsunami will be

necessary for the signal waves to travel a large distance. 10 KHz signals cannot be radiated efficiently because of the antenna size. The high energy signal waves (1GHz − 1000 GHz) penetrate the ionosphere. 10 MHz frequencies get reflected easily from the ionosphere. Hence‚ signal waves of such frequencies are suitable for beyond-the-horizon communication.

When used in stable mode‚ the 555 acts as a square wave oscillator whose clock rate is dependent on a time constant provided by two resistors and a capacitor. Many of the 555s weren’t providing a stable clock

Title: Earthquake Epicenter Lab Problem: How can we use seismic waves to determine the epicenter of an earthquake? Hypothesis: By using the arrival time of P-waves and S-waves from seismic stations‚ I can determine the epicenter of an earthquake. Data and Observations: After you have recorded the data for the seismographs you selected to review (Step 3 in the lab)‚ take a screenshot of your completed data table (or print it and send it directly to your instructor). You should also take a screenshot
