Frequency: a measure of how many waves pass in a certain amount of time. Read More Contents Wave Energy Fundamentals: How Waves Form Methods for Harnessing Wave Energy Obstacles to Wave Energy Wave Energy Fundamentals: How Waves Form As wind hits the water, ripples form. Then, wind...
As sound waves travel, they spread out in all directions in a curved wavefront. The farther they travel from the source, the more they spread and the quieter the sound becomes. However, high-frequency waves don't spread as much as low-frequency waves. Also, waves with long wavelengths gen...
Primary Voltage (Output Voltage)= 12-0-12 volts, that is equal to 24 volts. Output Frequency= 50 Hz Calculating Inverter Transformer Voltage, Current, Number of Turns Step#1:First we need to find the core area CA=1.152 ×√(24 × 10) = 18 sq.cm where 1.152 is a constant. We select...
Let's take a typical radar set designed to detect airplanes in flight. The radar set turns on its transmitter and shoots out a short, high-intensity burst of high-frequency radio waves. The burst might last a microsecond. The radar set then turns off its transmitter, turns on its receiver...
(See "How does a long-distance call work?" for a more detailed description.) Hand-generated! You know the hand crank on those old-fashioned telephones? It was used to generate the ring-signal AC wave and sound the bell at the other end! Creating Your Own Telephone Network Creating ...
Later movies followed the "Star Wars" model, using the surround track to create fantastic effects, as well as fill in background noise to establish a scene's setting. In later versions of the surround-sound system, theater owners could hook up asubwooferto handle extremely low-frequency sounds...
This article serves as an introduction to frequency modulated continuous wave (FMCW) radar generation within the 24 GHz ISM band. This includes the major building blocks required for this type of radar system such as ramp generation, transmit and receive stages, downconversion, and sampling. Introdu...

Sound-wave frequency - A higher wave frequency simply means that the air pressure fluctuates faster. We hear this as a higher pitch. When there are fewer fluctuations in a period of time, the pitch is lower. Air-pressure level - This is the wave's amplitude, which determines how loud the...
Outside the band of bias-t, such as 18GHz to 40GHz, the signal will have great loss and cannot achieve the expected effect of the amplifier. Therefore, when selecting bias tee, make sure that the passband range of bias is greater than or equal to the frequency range of broadband ...
