VCOs (Voltage Controlled Oscillators) are electronic devices that generate oscillating signals in response to changing DC voltages. The VCO-117 is a particular type of VCO that is useful in a wide variety of applications. This article will outline the application field and working principle of the VCO-117.

The VCO-117 is a versatile device that can be used in a variety of contexts. It is commonly used in radio navigation systems, providing signals to aircraft, boats and other vehicles to aid in navigation. It is also useful in communications systems since it can quickly generate a wide range of frequencies which can be used to modulate the signals. Additionally, VCO-117s are used in some sound synthesizers, providing a sound that is both rich in texture and able to vary its tone.

The VCO-117 is a digital voltage controlled oscillator, meaning that its frequency can be changed by varying the voltage level at its input terminals. The voltage source can either be a DC source, or an AC source with a frequency higher than the oscillating frequency. The DC source is commonly used for setting the initial frequency of the oscillator, while the AC source is used for varying the frequency over time.

The heart of the VCO-117 is its digital oscillator circuit. This circuit is composed of logic gates and counters, which are arranged in such a way that they generate a cyclically alternating pattern of logic signals. This pattern of logic signals is fed into a voltage-controlled amplifier, which amplifies the signal and outputs an oscillating signal with a frequency set by the voltage level at the input.

The VCO-117 is designed to be highly stable, meaning that changes in temperature, humidity or the supply voltage do not significantly affect the output frequency. It is also designed to be highly adjustable, so that the output frequency can be changed over a wide range of values without sacrificing stability.

The VCO-117 is also advantageous because it can generate signals with very low noise levels. This is important for applications such as navigation systems, where signals with a high signal-to-noise ratio are essential for accurate navigation.

In summary, the VCO-117 is a versatile device that can be used in a variety of contexts. It is useful for applications such as radio navigation systems, communications systems and sound synthesizers. Its digital oscillator circuit allows it to generate a wide range of frequencies with excellent stability, and it also offers very good noise performance.
