Different types of oscillator & it's application

1. Physics: I

3. The oscillator works on the principle of the oscillation and it is a
mechanical or electronic device. The periodic variation between the
two things is based on the changes in the energy. The oscillations are
used in the watches, radios, metal detectors and in many other devices
use the oscillators.
Oscillator

4. The oscillator converts the direct current from the power
supply to an alternating current and they are used in many of
the electronic devices. The signals used in the oscillators are a
sine wave and the square wave. The some of the examples are
the signals are broadcasted by the radio and television
transmitter, clocks which are used in the computers and in the
video games.

5. The different types of oscillators are mentioned below and some of them are
explained.
• Armstrong Oscillator
• Hartley oscillator
• Colpitts Oscillators
• Cross-Coupled Oscillator
• Dynatron Oscillator
• Meissner Oscillator
• Optoelectronic Oscillator
• Phase Shift Oscillator
• Wine Bridge Oscillator
• Robinson Oscillator
• Tri-Tet Oscillator

6. The Armstrong oscillator is an LC electronic oscillator and to generate this
oscillator we are using the inductor and the capacitor. The Armstrong
oscillator is known as the tickler oscillator because of the individual
features of the feedback signal should produce the oscillations are
magnetically coupled to the tank indicator. Let us consider the coupling is
weak, but the sustain oscillation is sufficient. The following equation shows
the oscillation frequency f. The Armstrong oscillator is also called as the
Meissner oscillator or tickler oscillator.
f = 1 / 2Π√LC

7. It is used to generate the sinusoidal output signals with a very
high frequency.
it is generally used as a local oscillator in receivers.
It is used in the radio and mobile communications.
Used as a source in signal generators and as a radio-frequency
oscillator in the medium- and high-frequency range.

8. The Hartley oscillator is an electronic oscillator. The frequency of this oscillation is
determined by the tuned circuit. The tuned circuit consists of the capacitor and inductor,
hence it is an LC oscillator. In 1915 by American engineer Ralph Hartley has invented this
oscillator. The features of the Hartley circuit are the tuned circuit consists of a single
capacitor in parallel with the two inductors which are in series. From the center
connection of the two inductors for oscillation purpose, the feedback signal is taken.

9. This oscillation will produce a desired range of
frequencies
The Hartley oscillators are used in the radio
frequency in a range of the 30Mhz
In radio receiver, this oscillator is used and it has
a wide range of frequency

10. The Colpitts Oscillator was by American engineering by Edwin H. Colpitts
in the year of 1918. This oscillator is a combination of both inductors and
capacitor. The features of the Colpitts Oscillator are the feedback for the
active devices and they are taken from the voltage divider and made up of
two capacitors which are in series across the inductor.

11. It is used to generate the sinusoidal output signals with a very
high frequency
Very wide range of frequencies is involved
It is used in the radio and mobile communications
In commercial purpose, many applications are used

12. The multi-wave oscillator was invented by the French engineer by Georges
Lakhovsky in the year of 1920 to 1940. He showed that the nucleus of the cell with
the filaments stands, it is very similar to the electronic oscillator and it has the
capability of receiving & sending the vibratory information. The multi-wave
oscillators are experimental, research for the historical instrument, and there is a
no medical claim is made. The multi-wave oscillator unit presents the printed
circuit board Golden ratio antenna.

13. The healing action of this oscillation is very bad because of the
holistically work
The healing process is done by all parts of the body
The MWO is used in many countries worldwide by individual
This oscillator is applied for the treatment of the cancer

14. The Wien bridge oscillator is used to find unknown values of components. In most of
the cases this oscillator is used in the audios. The oscillators are designed simply,
size is compressed and it has stable in frequency output. Hence the maximum output
frequency of the Wien bridge oscillator is 1MHz and this frequency is from the phase
shift oscillator. The total phase shift of the oscillator is from the 360° or 0°.

15.  It is used to measure the audio frequency.
 Wien bridge oscillator designs the long range of
frequencies
 It produces sine wave.
