The receiver is an indispensable key device in modern communication and technology fields. In various fields, receivers play an important role, from communication to navigation, from sensing to data processing. So what is a receiver? At the same time, I will share with you some common receivers in different fields.

1、 The concept and function of receivers

A receiver is a device or device whose main function is to receive, receive, or capture specific signals, information, or energy. Different types of receivers are designed to receive various types of signals, such as radio waves, light waves, sound waves, etc. These signals are converted into usable forms through the receiver so that we can further process and utilize them.

2、 The principle of the receiver

The principle of a receiver includes receiving signals, signal amplification, mixing, demodulation, filtering, as well as decoding and processing. Firstly, the receiver captures signals from the external environment and enhances the signal strength using an amplifier. Next, the signal is converted to a frequency range more suitable for processing through a mixer, and the signal is decoded using a demodulator to extract the carried information. Filters help remove unwanted frequency components and noise, while decoding and processing modules further decode and process the signal, ultimately converting it into usable raw information or data. Different types of receivers may adopt different principles and technologies to adapt to different signal types and application requirements.
