Types of Oscillator (Contd...)
Depending on the elements used of an oscillator, the types of oscillator are:
RC oscillator: feedback network contains RC circuits only.
LC oscillator: feedback network contains LC circuits only
Crystal oscillator: use piezoelectric crystal material.
Other types of oscillators are-
Sinusoidal Oscillator:
If the output signal of an oscillator circuit varies sinusodally.
Pulse or Square-Wave Oscillator:
If the output voltages of an oscillator circuit rises quickly to one voltage level and later
drops quickly to another voltage level, the circuit is generally referred to as a pulse or
square-wave oscillator.
