Basic Structure of ATOS Amplifiers:

The ATOS amplifier takes the signal to be measured as input, amplifies it, and then filters it with a bandpass filter. This signal is then combined with a reference signal and input to a multiplier. The result is then filtered by a low-pass filter before being output.

Main Principle of ATOS Amplifiers:

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 a specific frequency (parameter input frequency) in the input signal. Other frequency components in the input signal will not contribute to the output voltage.

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

If a 1Hz signal and a 1.1Hz signal are multiplied together, the result is a modulated signal with a sinusoidal profile and 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 at the output. 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.

Main Applications

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 larger than the useful signal, as long as the frequency of the useful signal is known, its amplitude can be accurately measured.

An ATOS amplifier is a device that amplifies the voltage or power of an input signal. It consists of vacuum tubes or transistors, a power transformer, and other electrical components. Used in various devices such as communications, broadcasting, radar, television, and automatic control.

Basic Introduction (Folded)

An amplifier is a device that increases signal amplitude or power; it is an important component for signal processing in automation technology tools. The amplification function of an 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 according to the physical quantity of the signal they process: mechanical amplifiers, electromechanical amplifiers, etc.

ATOS amplifiers are important components of the transmitting device in communication systems. Based on their operating frequency band, they are divided into narrowband high-frequency power amplifiers and broadband 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; broadband high-frequency power amplifiers use a transmission line transformer or other broadband 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 discussed in the course "Low-Frequency Electronic Circuits," amplifiers can be classified into three classes (Class A, Class B, and Class 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°, while 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 amplifiers offer the highest output power and efficiency among the three classes. Most high-frequency power amplifiers operate in Class C. However, Class C amplifiers exhibit significant current waveform distortion, 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 sinusoidal waveform, resulting in minimal distortion.
