Some devices have the receiver and transmitter built into the same device. Some devices use only a detector and register changes in emitted IR "patterns" (for example) to infer motion.

What is a digital receiver?
I have a Digit All World Satellite Receiver Model SFT-2000 of MPEG2. How do I convert to MPEG4?
How can you update your satellite receiver hi ican updeat all satellit receiver metabox?
If you are meaning an "fta" receiver it has to be "flashed" through your serial com port from your computer. R232
Antenna detect all frequency but why you can see only one channel?
A: The antenna is designed to receiver a specific band of frequency but the receiver will discriminate all signals except the one of interest otherwise all channels will fight for dominance
What is an example of how one law could explain all motion in the unverse?
Newton's F=ma is an example of a law that could explain all motion in the universe.
What is role of electronics in robotics?
Sensors, solenoids, motors and control computers are all electronic devices.
Types of medium that connects receiver to transmitter and its characteristic of all medium stated?
juhari
Is the telephone receiver in the earpiece?
The telephone receiver contains the earpiece. Virtually all receivers also contain the transmitter, which is the microphone that picks up the user's voice.
Does a solar powered FM Receiver work on the moon?
A solar-powered FM receiver transmitter is a transceiver (receiver/transmitter) that is set up for operation on FM (frequency modulation) and is powered by something like solar cells (photovoltaic devices).
Can a patriot gate opener be opened by a vehicle remote?
Yes, the Patriot gate operator can be opened by a vehicle remote. For this to work the vehicle must be equipped with a compatible transmitter to the receiver in the Patriot gate operator. Not all vehicles are equipped with the same transmitter so you need to verify the frequency of the receiver in the gate operator and then verify the vehicle is compatible.
Is a phone a solid?
Yes, all parts of a phone are solid (save for some intelligent phones' g-motion sensors which use liquid mercury as part of their sensors)
What is a transmittor?
Transmit: to send information or signals A transmitter is a electronic device that sends signals, data, etc. in order for us to receive & send information whether it is wired or wireless you have to have two components a transmiter and a receiver. lets look at some examples of transmitter and receivers. take your television for an example you can call it a receiver but the camera, and all the rest of the high tech devices that send pictures and other information to your TV can be call transmitter because they are sending information to your TV. And your radio whereas the radio is the receiver and the DJ at the radio station is transmitting music and other information . some inanimate objects that transmit can be found in your electric. the electricity that you use is being transmitter via all the sophisticated equipment found at your electric company transformers wires generator's
Can 10-15km distance be created between the remote and remote control car?
With a sufficiently powerful receiver and transmitter, it is possible. The problem will be the video feed needed to see where you are going, and getting a transmitter powerful enough to send all this information without requiring a radio license.
Why does your motion sensor security light stay on all night?
Either the sensor is not working properly or you have enough motion such as trees swaying, etc. to cause the sensors to constantly activate the lights.
Why do you use 4 - 20 mili ampere?
A 4-20ma current loop is often used in process control and monitoring systems to signal a value from one point to another. It operates using Kirchoff's current law, in that the transmitter can monitor the current on the loop, knowing that will be the same current at the receiver. Any deviations in reference voltage or ground differentials between transmitter and receiver can then be compensated for at the transmitter. The signal range starts at 4ma, so that the receiver can detect the 0ma condition representing a break in the wire. You can also have multiple receivers on the loop, all in series, so long as the delta voltage at each receiver does not contribute too much voltage to the overall loop. Each receiver will see the same current, again due to Kirchoff's current law.
What is a signal jammer?
A signal jammer or jamming transmitter is a small, low-powered transmitter that interfers with receivers in an area around the jammer. The radius of the area will depend on the power of the jammer. The jammer signal will be "seen" by the receiver and it won't then be able to "see" the little signal of the remotely located transmitter that it is trying to "look at" before you turn on your jammer. The jammer transmits a signal (without modulation - it's just the carrier wave) that radiates from the jammer pretty much in all directions (for an omni-directional antenna - which is what is usually on them). This small signal reaches all receivers within the area of its effective range and "swamps" the receivers in that area. Understand that the transmitters reaching out to receivers are generally "high power" units (their power varying depending on what they're designed to do). The jammer is low power. But because the signal from the transmitter is (almost always) a long, long way away from the receivers in the jammer's area, the signal from the transmitter is very tiny in that area. The jammer, on the other hand, has a "large" signal in that area because it's so close to those receivers. It's the amount of signal that gets to a receiver that is important. If a tiny transmitter (a jammer) is "right on top" of a receiver, it will "hit" that receiver hard compared to the tiny signal getting to that receiver from the (high powered) transmitter many miles away. The general rule for power for a transmitter getting to a receiver is that the signal strength is going to be the inverse sqare of the distance from that transmitter. That means that if you have "x" amount of signal at a given spot from a transmitter and them double your distance from the transmitter, the signal will be 1/d2 or 1/22 or 1/4th the amount you had before. Double the distance again and you're down to 1/16th the original amount of signal. A little transmitter works well to jam a receiver if it's right on top of it. It will "blind" the receiver to the "real" signal from the transmitter it is trying to capture. Jammers are generally a no-no, both ethically and legally. Use your head here and think through your options if you are planning some "experimental" electronics. It is the FCC (the Feds) that get down on individuals who interfere with communications. They play hard ball. Imagine interrupting air-to-ground communications and interfering with air traffic. They'd lock you up and throw away the key. Seriously.
How do wifi smart camera work?
Wifi smart camera transmit video through a radio frequency (RF) transmitter. The video is transmitted to a receiver that is linked to a built-in storage device or to cloud storage. You'll have easy access to all of your images or video clips via your monitor or receiver.
Wifi smart net camera: how does it works?
A radio (RF) transmitter is used to transmit the footage from a wifi smart net camera. The video is transmitted to a receiver via cloud storage or a built-in storage device. You'll have a simple link to all of your image or video clips through your monitor or receiver.
