What is blocking oscillator?
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.
What type of oscillator used in handwatches?
a crystal 32.768kHz oscillator.
Why rf choke is used in collpitts oscillator?
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
Where a colpitts oscillator is used?
the Colpitts oscillator , named after the inventor of the circuit , is characterised by the use of Two Capacitors in series which are then connected in parallel across the inductor of the resonant circuit for obtaining the required frequency. The junction of the two capacitors is used for the positive feedback used for generating the oscillations. This circuit is used for High frequency oscillators , mainly due to ease of obtaining required ratio of the two capacitor values as per the circuit design. Also the two capacitors in series reduces their total equivalent value , which is not a problem as in HF circuits as the values and size is comparatively low. For information , a corresponding Low frequency circuit is called a Hartley oscillator , also named after its inventor. This uses a tapped inductor & one capacitor for the resonant circuit, since it is more easier to fabricate large value tapped inductors , than to use two bulky ( since the value of capacitors in series is reduced ) capacitors necessary for the equivalent Colpitts oscillator.
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
What are the advantages of a Hartley oscillator?
advantages over what? Colpitts? Mostly the fact that it does not require a choke. A Hartley is more harmonic-rich than a Colpitts, so the main reason it is used lies in its (relative) ease of construction.

What type of feedback used in the oscillator circuit?
There are many different types of oscillator circuits, the majority of which use positive feedback.
What is transistor mos?
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
What is the probability that the transistor will last more than 550 hours?
The answer depends on the type of transistor, how intensively it is used as well as the manufacturer.
Which of these is not a type of signal used to send information through electricity?
transistor
