One easy fix is to add multiple access points (hardwired connections) and wireless repeater devices. This is much like adding telephone wiring from room-to-room to plug in more telephones, and using wireless phone stations throughout your home. Routers in general lack the transmitting power of ...
Generally, the monitoring of the electromagnetic pollution is performed by means of a suitable measurement chain constituted by an antenna connected to a traditional spectrum analyzer. The use of this kind of device to measure the power of digital modulated noise-like signals, such as WiMAX, ...
You may use electromagnetism every day if you charge a phone or tablet wirelessly. The charging pad creates a magnetic field. Your phone has an antenna that syncs with the charger, allowing a current to flow. As you may imagine, the electromagnetic coils inside devices like these are small,...
Visible light is part of the electromagnetic spectrum. The Sun is our main sources of light. The other sources for visible light are the moon and the stars. It is essential to realize that we cannot see ultraviolet or infrared wavelengths. However, we are able to detect the red and blue ...
The basic rule is that the tools you use have to be smaller than the things you're using them on.Photo: Inside an atom: electrons are the particles in shells (orbitals) around the nucleus (center).And the same goes for science. The smallest thing you can see with a microscope is ...

If a device, such as a television or radio, shows signs of incorrect operation, such as unwanted sounds being generated or a disrupted image, it is said to be suffering from electromagnetic interference (EMI). EMI may be conducted, through power or communication cables, or radiated. The diffe...
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
Use mnemonic devices like acronyms, as these are proven to increase learning efficiency.[8] Example #1 If you want to memorize the electromagnetic spectrum in order of increasing frequency, you could use this acronym/sentence: RagingMartiansInvadedVenusUsingX-rayGuns ...
In LTspice, an arbitrary behavioral voltage source can be used to create an AM waveform. AM waveforms can be demodulated using a multiplier followed by a low-pass filter. A simpler (and lower-cost) approach is to use a leaky peak detector, i.e., a peak detector with...
