Radar receivers have to be tuned to the precise frequency of the transmitter, in order to get the best detection and thus the best picture. The transmitter generates microwaves from a device called a magnetron. The exact frequency can vary with age and temperature. To pick up the echo generated from the pulsed microwave, the receiver is able to be tuned, to allow for differences in transmitter frequency. The control on the radar receiver display, called 'tuning', actually alters the receiver frequency, not the transmitter frequency.
the frequency difference between the transmitter and the receiver without any noise or distortion
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
To change the frequency on a radio controller car, you change the crystal in the transmitter and receiver.
when an electron drops from a higher energy state to a lower it emits a fixed frequency photon Gallium Arsenic Silicon Carbon have bright lines in a band of infrared can be varied colors depending on proportions this is monochromatic IR if you put parallel mirrors on either side of the the activated atoms you get a laser co2 gas laser ... Led Solid laser although IR is produced by burning sugar in a body and digital cameras can see that too

Having a built-in ir transmitter receiver is a fabulous idea
It is a the RF output of a transmitter that is tuned to a distanced receiver, it have to be in resonance with the transmitter signal to be able to receive the signal
Yes, the IR transmitter doesn't care how many IR headphones are in the room.
The 555 is a timer and oscillator chip capable of sourcing and sinking 200 milliamperes, and is useful for pulsing an infrared LED to power an infrared transmitter. It can be pulse width modulated or otherwise controlled via the various control pins. See: http://talkingelectronics.com/FreeProjects/555/555-P3.html in most cases the IR detector used is TSOP sensors which works only on a specified frequency of 38KHz. So by using 555 timer, we can design the circuit very easly to work @ 38KHz. dats why in 555 is used in many IR txns.
Yes, you can attach multiple devices to an IR transmitter, but it depends on the specific model and its capabilities. Some IR transmitters are designed to control multiple devices simultaneously, while others may require a separate transmitter for each device. Additionally, if using a universal remote, it may be possible to program it to control multiple devices through a single IR transmitter. Always check the specifications and compatibility of your equipment before attempting to connect multiple devices.
A transmitter sends a radio frequency to a robot.

depends on frequency and power
In general they will be the same.

No, TV remotes use IR light and/or RF transmitter.
