Which diode is used in frequency tuning application?
The varactor diode is used in frequency tuning applications. Its effective capacitance is a function of the reverse bias voltage across it.
What type of diode is often used in television remote-control devices?
infrared diode
Which detector is used in tv receivers?
Diode detector
What meaning led?
light emitting diode and its a diode that emitting the light when the current passes through it and it used in the TV screen

What are some practical uses of diodes?
Diodes are largely used for changing AC into DC. A half wave diode bridge will use two diodes for this purpose. A full wave bridge uses four diodes to accomplish this task.See related links below.
What is the function of varactor diode?
Voltage controlled variable capacitor. Usually used for dynamic tuning of resonant circuits.
Why can't a conventional pn junction be used for high frequency switching applications?
If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.
What is the wavelength of a tv remote?
The peak wavelength of the IR diode used in TV remotes are usually around 940 nanometers.
What is Light Emitting Diode used for?
leds are used for a lot of different products,mp3players,lamps,night lights TVs computers, etc.leds are used to create light or power.
What is the Difference between lcd and light-emitting diode?
LCD is short for Liquid Crystal Display, and is used in screens and TVs. LED, or light emitting diode is used as an form for indicator.For more information:LCD - http://en.wikipedia.org/wiki/Liquid_crystal_displayLED - http://en.wikipedia.org/wiki/Light-emitting_diode
What is the use of crystal detector in electronics?
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
