A diode is used primarily as a Rectifier
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
The main function of a transistor is to amplify a signal. Two legs of it can also be used as a diode.
diode detector for am demodulation
For answering this question we have to consider the constant voltage drop model of the diode which says that if voltage across diode is less then its cut in voltage than assume diode to be open circuit and if it is greater then assume diode to be short circuit.Till the input voltage is less than the cut in voltage, diode is open circuit(thus no current through the circuit). Thus entire input voltage appears across the diode as output.When input voltage is greater than or equal to cut in voltage, then short circuit the diode. Thus, there will be no voltage drop across the diode as output.Thus cut in voltage decides when to consider the diode open circuit and when short circuit. It decides when the diode will have output when it will not.

A diode-clipping circuit is used to skip some portion of the signal (e.g. the half way/full way rectifiers rectify the '-ve' or '+ve' part of the signal). A diode-clamping circuit is used to add some signals to the original signal.
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
the important of diode in electrical circuit is to,,flow the current being regulated to the resistance of the electricity ,,from ac to dc..

It converts light into an electrical signal. Opposite of what an LED does. David Gallardo ATX
A diode.
A varactor diode is a P-N junction diode that changes its capacitance and the series resistance as the bias applied to the diode is varied. The property of capacitance change is utilized to achieve a change in the frequency and/or the phase of an electrical circuit
A diode is an electronic component that, when integrated into an electrical circuit, allows electricity to flow in one direction only.
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
A diode is an electrical device that permits an electrical current to flow through it, end to end in both directions. The flow of electricity will always be greater in one direction than the other. Diodes are used as a form of protection in circuit valves.
