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.
for high frequency applications(RF oscillator) we use BF 194
whatever works at the desired operating frequency
oscillator frequency is different.crystal working piezo electric effect
for high frequency applications(RF oscillator) we use BF 194
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.

A phase-shift oscillator using a PNP transistor consists of an RC network in the feedback path, a PNP transistor biased to operate in the active region, and a network of resistors and capacitors that provide the required phase shift for oscillation. The RC network introduces a 180-degree phase shift at the desired frequency, and the transistor provides the additional 180-degree phase shift needed for sustained oscillation. By properly selecting the values of resistors and capacitors, along with biasing the transistor correctly, a stable sinusoidal oscillation can be achieved.
This mechanism is how a transistor works.
