What is LM566?
LM566 VCO: Voltage Controlled Oscillator is a general purpose voltage controlled oscillator which may be used to generate square and triangular waves, the frequency of which is a very linear function of a control voltage. The frequency is also a function of an external resistor and capacitor.
Which of the following IC can be used as a VCO?
Voltage controlled oscillator using LM566 IC It can be used to generates square and triangle waveforms simultaneously. The frequency of the output waveform can be adjusted using an external control voltage.

Why voltage-controlled oscillator is used?
VCOs are used in function generators, phase-locked loops including frequency synthesizers used in communication equipment and the production of electronic music, to generate variable tones in synthesizers.
Why VCO is used in FM generation?
VCO is used to generate In this type of modulation, the frequency of the carrier is varied directly by the instantaneous voltage of the modulating signal i.e., the instantaneous frequency of the output signal is directly proportional to the voltage of the input modulating signal.
What is VCO in FM?
Glossary Term: FM Modulator Definition. A voltage-controlled oscillator (VCO) is an electronic oscillator whose output frequency is proportional to its input voltage. An oscillator produces a periodic AC signal, and in VCOs, the oscillation frequency is determined by voltage.
What is the features of 566 VCO?
FEATURES of 566 VCO: stable center frequency. Highly linear triangle wave output. Frequency programming using a resistor or capacitor voltage or current. Frequency adjustable over 10-to-1 range with the same capacitor.
What is the principal of VCO?
Basic Working principle of Sawtooth waveform generator VCO The input is given in form a voltage that can be controlled. This voltage is converted to a current signal and is applied to the capacitor. As the current passes through the capacitor, it starts charging and a voltage starts building across it.
What is the purpose of VCO and PLL?
A PLL is a feedback system that includes a VCO, phase detector, and low pass filter within its loop. Its purpose is to force the VCO to replicate and track the frequency and phase at the input when in lock. The PLL is a control system allowing one oscillator to track with another.
