AI Technical Summary

Technical Problem

Shortwave signal transmission is affected by factors such as daytime, climate, season, and social activities, resulting in signal fluctuations and making it impossible to accurately measure the actual state changes of the receiving equipment.

Method used

A signal conditioning device is designed, including a signal preselection unit, a switching unit, a signal amplification unit, and a controllable gain attenuation unit. The device uses a microprocessor to control the preprocessing, amplification, and attenuation of the signal to achieve conditioning of shortwave signals. The conditioning range is -31dB to +19dB, which enhances the out-of-band rejection and gain adjustment capabilities of the device.

Benefits of technology

It effectively avoids the generation of intermodulation signals, improves the ability to receive weak signals, enhances the receiver's sensitivity and dynamic range, and is suitable for high-performance receivers.
