Arrays

Arrays are a type of signal transducer that transforms a range of analog signals into multiple signals. They play an important role in signal processing applications, providing flexibility and speed in the transformation process. The PM620-08 is a popular and versatile array transducer that can process a wide range of signals, from sine waves to complex digital signals.

Application Field

The PM620-08 is widely used in many signal processing application areas, including data acquisition for digital systems, telecommunications, radio frequency signal processing, medical imaging, industrial process control, and signal analysis. It is also used to accurately measure the amplitude and waveform of analog and digital signals. In addition, the PM620-08 is used to boost the accuracy of digital systems by increasing the signal-to-noise ratio. Thus, this transducer can be applied to a wide range of applications.

Working Principle

The PM620-08 is composed of several integrated circuits: four op-amps, three transformers, and two analog multipliers. It works by sensing the input signal’s magnitude and phase, and then performing the necessary calculations in order to produce its output. The op-amps and transformers provide the necessary signal amplification and filtering, while the analog multipliers are used to generate the required output signals from the input signal. For example, the PM620-08 can be used to detect and measure the frequency of an AC signal, and then use the calculation module to produce the desired output signal.

The PM620-08 also supports a process control function, allowing the transducer to adjust the output signal based on feedback from the input signal. Moreover, it has three operational modes: single-channel, four-channel, and eight-channel, which can be used to process a variety of signals. The transducer also provides a high degree of accuracy and stability, as well as an adjustable gain control.
