Anonymous users2024-02-041. Definition: Encyclopedia has, generally speaking, it is the key component of the signal source.
The signal source provides signals on the test platform and application-oriented products, which is to rely on the signal generator and peripheral circuits (such as power supply circuits, LCD displays, key touch screen input circuits, etc.) to generate, process, transmit and display the signals. Dou Bixu.
The DDS signal generator uses Direct Digital Synthesis (DDS) technology to improve the frequency stability and accuracy of the signal generator to the same level as the reference frequency, and can perform fine frequency adjustment over a wide frequency range.
Second, the field of application:
Communications, navigation, radar, remote control telemetry, electronic countermeasures, instrumentation.
3. Programming: According to different signal requirements, the signal can be changed, so that the signal generator can output the desired signal waveform (for example, the waveform, amplitude, phase, duty cycle, etc. of the output signal can be changed by programming the air fuel).

Hello! See what you want to do?
In view of the development status of the control method of classroom lighting, especially the development status of intelligent control of classroom lighting, this study analyzes the principle and implementation method of intelligent control of classroom lighting, puts forward the design idea of classroom lighting intelligent control system based on single-chip microcomputer, and develops the hardware device and corresponding software of intelligent control system on this basis. The system uses AT89C52 single-chip microcomputer as the intelligent component of the control device, uses pyrothermal infrared human body sensor to detect the existence of human body, and uses a circuit composed of photosensitive transistor to detect the intensity of ambient light. According to the conditions of reasonable lighting in the classroom, the system completes the intelligent control of the classroom lighting circuit through the recognition and intelligent judgment of the presence signal of the human body and the ambient light signal, and avoids a large waste of electricity in the classroom. The system also has a variety of alarm functions; At the same time, anti-interference measures such as software and hardware "watchdog" technology are also adopted. >>>More
