A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.
for high frequency applications(RF oscillator) we use BF 194
This mechanism is how a transistor works.
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
The UM66 is an electronic doorbell. It requires a button for the door, a single transistor, a battery and a speaker.
The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.
i will put tank ckt and give it to transistor via positive feedback
amplifier, switch, oscillator, etc.
Here's a simple one:
whatever works at the desired operating frequency
for high frequency applications(RF oscillator) we use BF 194
oscillator frequency is different.crystal working piezo electric effect
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
for high frequency applications(RF oscillator) we use BF 194
Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.

This mechanism is how a transistor works.
