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 communications, broadcasting, radar, television, and automatic control.

ATOS Amplifier Basic Introduction

ATOS amplifiers are devices that increase the amplitude or power of signals. They are important components in signal processing tools in automation technology. The amplification function of the amplifier is achieved by controlling the energy source with the input signal; the power consumption required for amplification is provided by the energy source. For a linear amplifier, the output is a reproduction and enhancement of the input signal. For a nonlinear amplifier, the output has a certain functional relationship with the input signal. Amplifiers are classified into mechanical amplifiers and electromechanical amplifiers according to the physical quantity of the signal they process.

The main functions of an ATOS amplifier are:

1. A device that amplifies the voltage or power of an input signal, composed of vacuum tubes or transistors, power transformers, and other electrical components. It is used in various devices such as communications, broadcasting, radar, television, and automatic control.

The principle of an ATOS amplifier: A high-frequency power amplifier is used in the final stage of a transmitter. Its function is to amplify the high-frequency modulated wave 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 an important component of the transmitting device in a communication system. High-frequency power amplifiers are classified into two types based on their operating frequency band: narrowband and wideband. Narrowband high-frequency power amplifiers typically use a frequency-selective circuit with frequency filtering capabilities as their 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 their 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 classes (A, B, and C) based on their current conduction angle. Class A amplifiers have a current conduction angle of 360°, suitable for small-signal, low-power amplification. Class B amplifiers have a current conduction angle of approximately 180°; Class C amplifiers have a current conduction angle less than 180°. Both Class B and Class C are suitable for high-power operation. Class C has the highest output power and efficiency among the three operating classes. Most high-frequency power amplifiers operate in Class C. However, Class C amplifiers have excessively distorted current waveforms, 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.

Historical background of ATOS amplifiers:

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. 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, 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 emerged. These LIAs simply used digital filters to suppress noise in the signal input, reference signal, and output channels, or added 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 allowed for computer control, monitoring, and display, but the core phase-sensitive detector (PSD) or demodulator was still implemented using analog electronics, making it essentially an ALIA. It wasn't until phase-sensitive detectors or demodulators were implemented using digital signal processing that digital lock-in amplifiers (DLIAs) appeared. 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.

The basic structure of an ATOS amplifier:

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

The main principle of an ATOS amplifier:

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 (the input frequency). Other frequency components of the input signal contribute nothing to the output voltage.

Two sinusoidal signals, both 1Hz and 90 degrees out of phase, multiplied together, result in a sinusoidal signal with a DC bias.

Multiplying a 1Hz signal and a 1.1Hz signal results in a modulated signal with a sinusoidal profile and zero DC bias.

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 applied to the multiplier output, all AC components are filtered out, leaving a DC component that is simply proportional to the amplitude of the input signal at that specific frequency.

The main applications of an ATOS amplifier:

Primarily used for detecting weak signals with very low signal-to-noise ratios. Even if the useful signal is submerged in noise, and 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 that signal can be accurately measured.
