Oscillators:
Oscillator is
defined as a circuit that converts DC energy into AC energy of desired frequency.
Or
Oscillator is an electronic device which generates
oscillations of desired frequency.
Classification
of Oscillators:
Oscillator can
be classified in the following ways.
1. According to generated wave forms:
·
Sine
wave oscillators
·
Non-sinusoidal
oscillators.
2. According to associated oscillators
circuit components:
·
RC
phase shift oscillators:
Ø RC phase shift oscillators.
Ø Wein bridge oscillators.
·
LC
oscillators:
Ø Hartley oscillators.
Ø Colpitts oscillators.
Ø LC oscillators.
·
Crystal
oscillators:
3. According to frequency range:
·
Audio
frequency oscillators (AF)- 20Hz to 20kHz.
·
Radio
frequency oscillators (RF)- 20kHz to 30Mhz.
·
Very
high frequency oscillators (VHF)- 30Mhz to 300Mhz.
·
Ultra-high
frequency oscillators (UHF)- 300Mhz to 3000Mhz
So, these
are the classifications of the oscillators.
