What does AVCO mean in UNCLASSIFIED
AVCO (Active Voltage Controlled Oscillator) is an electronic circuit that generates a periodic waveform whose frequency is controlled by a voltage. It is a type of oscillator that uses a voltage-controlled amplifier (VCA) to control the gain of a feedback loop. This allows the frequency of the oscillator to be varied by changing the voltage applied to the VCA.

Essential Questions and Answers on Active Voltage Controlled Oscillator in "MISCELLANEOUS»UNFILED"
What is an Active Voltage Controlled Oscillator (AVCO)?
An Active Voltage Controlled Oscillator (AVCO) is an electronic oscillator that utilizes an active device, such as a transistor or operational amplifier, to generate and control its oscillations. The frequency of the oscillations is determined by the voltage applied to the control input.
How does an AVCO work?
In an AVCO, the active device acts as an amplifier with positive feedback. When a small voltage is applied to the control input, it is amplified and fed back into the oscillator circuit, creating a sustained oscillation. The frequency of the oscillation is inversely proportional to the capacitance in the feedback loop and directly proportional to the gain of the active device.
What are the advantages of using an AVCO?
AVCOs offer several advantages:
- Wide frequency range: They can generate oscillations over a wide range of frequencies, from very low frequencies (VLFs) to ultra-high frequencies (UHFs).
- Voltage control: The frequency of oscillation can be precisely controlled by varying the control voltage.
- Stability: AVCOs are relatively stable and can maintain their frequency over a wide range of temperature and operating conditions.
- Low power consumption: They require relatively low power to operate, making them suitable for portable and battery-powered devices.
What are the applications of AVCOs?
AVCOs are used in various applications, including:
- Frequency modulation (FM) transmitters
- Phase-locked loops (PLLs)
- Frequency synthesizers
- Test and measurement equipment
- Medical imaging systems
Final Words: AVCOs are versatile and useful electronic circuits that can be used in a variety of applications. They are relatively easy to design and build, and they offer a number of advantages over other types of oscillators.
