RFID (radio frequency identification) is a form ofwirelesscommunication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. How does RFID work? Every RFID system consists o...
Full-duplex transceivers.The radio transmitter and receiver can work in parallel. Transmission and reception take place on different radio frequencies. This mode is observed in handheld and mobile two-way radios. The difference between half-duplex and full-duplex data transmission What role do transce...
Tuners work using a principle called resonance. That is, tuners resonate at, and amplify, one particular frequency and ignore all the other frequencies in the air. It is easy to create a resonator with a capacitor and an inductor. The tuner causes the radio to receive just one sine wave ...
(see, for example, Steve Guttenberg's articleHow do you like your headphone sound: Accurate or bassy?). Mass-market phones and earbuds may well be designed to emphasize bass frequencies—which is great if that's what you like and horrible if not. Beware of products that draw too much ...
These tags also operate at different frequencies, which impacts range: the higher the frequency, the farther the scanning range.There are also semi-passive RFID tags, which work like passive tags but include a battery to extend their range. Passive tags remain the most common choice because ...
You will find out what frequencies are used for RC toys, what the different components are and how they all work together. You will also learn what the difference between radio control and remote control is when talking about toys or models. Types of RC Toys RC toys come in a large ...
Lossy audio codecs may remove frequencies from the original recording that most people can't hear, around 20 Hz to 20,000 Hz. While that may help save on streaming bandwidth, it can cause problems, too. You may have experienced some side effects of file compression while you watch a show...
Often just called a Sectional or Sectional Chart, these maps are updated every 6 months and show things like terrain elevations, airports, radio frequencies, latitude & longitude, and airspace classes. Nashville’s (BNA) Class C Airport. The innermost magenta circle that surrounds the airport den...
How does Bluetooth work?Bluetooth sends and receives radio waves in a band of 79 different frequencies (channels) centered on 2.45 GHz, set apart from radio, television, and cellphones, and reserved for use by industrial, scientific, and medical gadgets. [3] Don't worry: you're not going...
