Are high-frequency electronic circuits useful? [Copy link]

This course is quite difficult. Can anyone who has taken this course give me some advice on whether this course is useful?

It is very useful for those who need it, but it is of no use to those who don’t need it.

What is so useful? The harder it is to get started, the higher the threshold, the more valuable it is.

Haha, the starting point of this question is a bit tangled. As far as I know, haha, high-frequency electronic circuits are the basic courses for communication and electronic information related majors. They are the basis of hardware implementation and are still very useful. After all, they are basic courses. High-rise buildings are built from the ground, and the foundation is very important~~

There is nothing wrong with learning more. You don't have to learn more thoroughly, but at least you have to understand it.

High-frequency electronic circuits are widely used in many fields, especially in communications, radio, radar, satellites, and aerospace. They are used to transmit and process high-frequency signals, which have very high frequencies and short wavelengths and can be transmitted through the air by electromagnetic waves. This makes high-frequency electronic circuits very important because they can help us achieve tasks such as wireless communication, signal processing, and radar detection.

In radio communications, high-frequency electronic circuits are used to receive and send radio signals. These signals can be voice, data, or video, modulated into high-frequency signals for transmission. Receivers use high-frequency electronic circuits to amplify and demodulate the signals so that the original information can be restored at the receiving end. Transmitters use high-frequency electronic circuits to generate and modulate high-frequency signals to transmit information to remote receivers.

In the field of radar, high-frequency electronic circuits are used to transmit and receive radar signals to detect and track targets. Radar systems use high-frequency electronic circuits to generate and amplify high-frequency pulse signals to send and receive echoes in the air. These signals are processed to provide information about the target, such as distance, speed and direction.

Therefore, it can be said that high-frequency electronic circuits play a very important role in modern communication and radar technology. They not only allow us to perform wireless communications and signal processing, but also help us achieve a series of key tasks in fields such as aerospace and national defense.

In general, learning electronic circuits requires patience and persistence, and requires constant practice and experimentation. Mastering basic mathematics and physics knowledge is a prerequisite. By learning the basic principles of electronics and practical operations, you can gradually improve your ability to design and analyze circuits, and then master advanced electronics.

This will definitely be useful. Those who work in electronic circuit development and radio frequency testing need this knowledge.
