A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency.
Voltage controlled oscillator circuit diagram.
Consequently a vco can be used for frequency modulation fm or phase modulation pm by applying a modulating signal to the control input.
The frequency of this waveform is varied by varying the magnitude of the.
A voltage controlled oscillator is an oscillator with an output signal whose output can be varied over a range which is controlled by the input dc voltage.
It is an oscillator whose output frequency is directly related to the voltage at its input.
This waveform can either be of sine triangle or even a saw tooth type.
The applied input voltage determines the instantaneous oscillation frequency.
By varying the input dc.
While using a single supply the supply voltage range is from 10v to 24v.
Some of the most common oscillator circuits are lc circuit tank circuit etc.
The lm566 ic can be operated from a single supply or dual supply.
A vco is also an integral part of a phase locked.
Voltage controlled oscillator using lm566.
A voltage controlled oscillator vco is an electronic oscillator whose oscillation frequency is controlled by a voltage input.
The ic has a very linear modulation characteristic and has excellent thermal stability.
The circuit diagram of a voltage controlled oscillator using lm566 is shown in the figure below.
