the function of a diode detector is to detect stuff
difference between detector and diode
diode detector for am demodulation
the main function of the diode is to allow current to flow in just one direction and oppose the flow of current in negative direction.In short diode rectifies the current..
This appears to be a Motorola diode, and a data sheet is available from that company.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
difference between detector and diode
diode detector for am demodulation
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
Diode detector
A diode is used primarily as a Rectifier
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.
A diode is basically any of a great variety of circuit element that has two electrical connections. They serve many different functions. The simplest type, the rectifier diode, only lets current through in one direction - but there are other specialized diodes, like the LED (light-emitting diode), to name but one. A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.
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.
