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.
To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.
yes electronics engineering is harder than mechanical engg......... because in electronics we study all the fundamental formulas of mechanical or we use all the bais concepts of mechanical to derive electronics features or to clear electronics basics.... but we dont use electronic's fundamentals in mechanical engg..... conclusion is that.. for electronics engg we must have the knowlege of mechanical and electronics both ..... then we can be able to clear all the concepts or all the queries of electronis basics .... but for mechanical we dont use the knowledge of electronics...... mechanical is a straight branch.... while in electronics thers id a mixture of (electronics+mechanical+computer+chemical) other branches...... if we wanna be master of electronics world we must have the knowledge of all (electronics+mechanical+computer+chemical) but for mechanical ... we must have the knowledge for basic mechanics statics and all... electronics knowledge is not must for mechanical...... so electronics is more tough branch than mechanical....... for more answers of ur queries do mail in ...

in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics . in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages
Perhaps a two-stage process. Firstly, gain access to the electrical output in the smoke detector, that drives the noise transducer. Use this (amplified?) to drive the mechanism of your electrically-operated lock.
WE CAN use the balanced modulator & also the double balanced modulator(DBM) THANKS. ASMA
The ED spectrometer is comprised of a liquid nitrogen (LN2) dewar, Si crystal, and preamplifier. The special Si crystal is mounted at the end of the detector located closest to the specimen. When X-rays strike the Si crystal very small signals are produced. These signals are amplified in the detector and sent on to the analysis electronics in the computer for further processing. The crystal is cooled by a cold finger, an extension of the LN2 dewar. Liquid nitrogen cools and therefore stabilizes the electronic properties of the crystal, improving the measurements of minute X-ray signals.
Yes, you can use a metal detector in the rain if....... The detector is made for underwater use. If the metal detector is made for land use, put a cover over the electronics housing. Many of the top manufacturers sell rain-proof covers. Be sure your headphones are waterproof!
when you enter through to find the mayors badge, its righ below you
We use the IC1 555 in LPG gas detector to detect the leaking gases.
A crystal receiver does not run on electricity. It is simply powered by the radio waves it is receiving. A large antenna is used to receive the signal and moves the signal to the crystal detector or diode.
On the Beach, towards the lower left of the Beach right next to that clam store.
Yep it does.
yes

you use your detector and go to the crystal room and go to the stand then go to carl and see his footprint he will say no then ask him for something to eat then go to the jam jar then make him step in it
