there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area or height of the peak only at two different wavelengths. But that wavelengths also to be selected before injecting the solution.
it is a rectify diode
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
difference between detector and diode
the function of a diode detector is to detect stuff
diode detector for am demodulation
Diode detector
0a79 ( germanium diode )in glass construction form is used in AM detector circuits.
The 1N34 is a germanium signal diode, so it would be used as a detector/mixer in a.m. reception for example.
The question is not specific enough. I think you mean in a simple crystal radio, using a diode detector. The small value capacitance after the detector, takes any stray RF frequency down to earth, before being passed onto the headphones, where it would otherwise swamp the headphone coils.
This type of smoke detector is more sensitive. It uses a laser diode in the sensor instead of an LED which allows it to be much more sensitive.
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.
The 2N5777 is a Darlington silicon NPN photo detector, or, if you prefer a photoDarlington. A link is provided to a bit of data on this device.

demodulator circuit is a circuit which is used for remove all high frequency components from modulated signal.
