What is radar tuning?
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.
What is coarse frequency offset?
the frequency difference between the transmitter and the receiver without any noise or distortion
What is FM transmitter and what are the different FM transmitters?
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.
How do you change the frequency on a radio controlled car?
To change the frequency on a radio controller car, you change the crystal in the transmitter and receiver.
How are IR rays produced in transmitter circuit of IR alarm?
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
What is the frequency of simple transmitter?
40 kHz
Does the Lenovo t500 have a built-in ir transmitter receiver?
Having a built-in ir transmitter receiver is a fabulous idea
What is resonating frequency?
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
Can you connect 4 headphones to the same ir DVD player?
Yes, the IR transmitter doesn't care how many IR headphones are in the room.
Why using 555 timer in ir transmitter?
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.
Can I attach more than one device to IR transmitter?
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.
What sends a radio frequency to a robot?
A transmitter sends a radio frequency to a robot.

What is range of rf transmitter and receiver?
depends on frequency and power
Why Transmitter frequency lower than Receiver?
In general they will be the same.
What is coarse frequency offset?
the frequency difference between the transmitter and the receiver without any noise or distortion
Does leaser diode use in tv remote?
No, TV remotes use IR light and/or RF transmitter.
