ATOS amplifiers are devices that amplify the voltage or power of input signals. They consist of vacuum tubes or transistors, power transformers, and other electrical components. They are used in various devices such as communication, broadcasting, radar, television, and automatic control.

Main functions of ATOS amplifiers:

1. Devices that amplify the voltage or power of input signals, consisting of vacuum tubes or transistors, power transformers, and other electrical components. Used in various devices such as communication, broadcasting, radar, television, and automatic control.

Principle: High-frequency power amplifiers are used in the final stage of transmitters. Their function is to amplify the high-frequency modulated signal to meet the transmission power requirements, and then radiate it into space through an antenna, ensuring that receivers within a certain area can receive a satisfactory signal level without interfering with communication on adjacent channels.

High-frequency power amplifiers are important components of transmitting devices in communication systems. Based on their operating frequency band, they are divided into narrowband high-frequency power amplifiers and wideband high-frequency power amplifiers. Narrowband high-frequency power amplifiers typically use a frequency-selective circuit with frequency filtering as the output circuit, hence they are also called tuned power amplifiers or resonant power amplifiers. Wideband high-frequency power amplifiers use a transmission line transformer or other wideband matching circuits as the output circuit, therefore they are also called untuned power amplifiers. A high-frequency power amplifier is an energy conversion device that converts DC energy supplied by a power source into high-frequency AC output. As known in the course "Low-Frequency Electronic Circuits," amplifiers can be classified into three operating classes (A, B, and C) according to their current conduction angle. Class A amplifiers have a current conduction angle of 360° and are suitable for small-signal, low-power amplification. The current-carrying angle of a Class B amplifier is approximately 180°; that of a Class C amplifier is less than 180°. Both Class B and Class C amplifiers are suitable for high-power operation. Class C amplifiers offer the highest output power and efficiency among the three operating modes. Most high-frequency power amplifiers operate in Class C. However, the current waveform distortion of Class C amplifiers is too high, making them unsuitable for low-frequency power amplification. They are only suitable for resonant power amplification using a tuned circuit as the load. Because the tuned circuit has filtering capabilities, the circuit current and voltage remain very close to a sine wave, resulting in minimal distortion.

2. A tool used to enlarge or reduce figures when drawing. Also called a magnifying ruler.

Historical Background

The invention of the first lock-in amplifier (LIA) by EGG PARC (the predecessor of SIGNAL RECOVERY) in 1962 marked a significant breakthrough in weak signal detection technology, greatly promoting the development of basic science and engineering technology. Currently, the continuous advancement of weak signal detection technology and instruments has led to its widespread application in many scientific and technological fields. Future scientific research will not only place higher demands on weak signal detection technology, but new scientific and technological developments will also, in turn, promote the emergence of new principles and methods for weak signal detection.

Early LIAs were implemented using analog circuits. With the development of digital technology, hybrid analog-digital LIAs have emerged. These LIAs simply use digital filters to suppress noise in the signal input, reference signal, and output channels, or they add analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and various general-purpose digital interface functions to the analog lock-in amplifier (ALIA). This allows for computer control, monitoring, and display, but the core phase-sensitive detector (PSD) or demodulator is still implemented using analog electronics, making it essentially an ALIA. Until phase-sensitive detectors or demodulators were implemented using digital signal processing, digital lock-in amplifiers (DLIAs) emerged. DLIAs have many significant advantages over ALIs and are highly favored, becoming a hot topic in weak signal detection research. However, in some special applications, ALIs still play an irreplaceable role compared to DLIAs.

Main Applications of ATOS Amplifiers:

Primarily used for detecting weak signals with very low signal-to-noise ratios. Even if the useful signal is submerged in noise, or even if the noise signal is much stronger than the useful signal, as long as the frequency of the useful signal is known, the amplitude of the signal can be accurately measured.

Basic Structure of ATOS Amplifiers:

The input signal to be measured is amplified and bandpass filtered, then input together with a reference signal into a multiplier. The result is then filtered by a low-pass filter before being output.

Main Principle (Folded Edit Section)

A lock-in amplifier is essentially an analog Fourier transform. The output of a lock-in amplifier is a DC voltage, proportional to the amplitude of the input signal at a specific frequency (parameter input frequency). Other frequency components in the input signal will not contribute to the output voltage.

Two sinusoidal signals, both 1Hz in frequency and with a 90-degree phase difference, multiplied by a multiplier, result in a sinusoidal signal with DC bias.

Multiplying a 1Hz signal and a 1.1Hz signal using a multiplier results in a sinusoidal modulated signal with a DC bias of 0.

Only signals with the same frequency as the reference signal will produce a DC bias at the multiplier output; other signals will produce AC signals. If a low-pass filter is added to the multiplier output, all AC signal components will be filtered out, leaving a DC component that is simply proportional to the amplitude of the specific frequency component in the input signal.
