Introduction to YB-3266A Communication Principle Experiment System
The YB-3266A Communication Principle Experiment System is an educational apparatus designed for university-level courses in communication and electronics engineering. Featuring a modular architecture, it integrates fundamental functional units including digital signal source, digital modulation/demodulation, digital/analog phase-locked loop, PCM encoding/decoding, and serial communication interface. This system enables comprehensive experiments covering 2ASK/2FSK/2PSK/2DPSK modulation techniques, carrier synchronization via analog PLL, bit synchronization through digital PLL, as well as time-division multiplexing baseband communication and duplex voice transmission. The transparent design allows students to observe signal processing at each stage while connecting modules flexibly to construct complete communication systems. With its user-friendly interface and robust construction, the equipment effectively bridges theoretical concepts with practical implementation, serving as an ideal platform for both fundamental experiments and innovative project development in communication engineering education.135
教学功能特点
该实验箱突出理论与实践结合的教学价值，通过创造设计性实验培养学生系统思维能力。其硬件平台可清晰展示通信系统各环节信号变换过程，如PCM编译码单元能直观呈现语音信号数字化处理流程，而数字调制单元则完整演示了基带信号到频带信号的转换机制。实验内容设置遵循由浅入深原则，从单一技术点验证逐步过渡到复杂通信系统搭建，例如通过组合时分复用与PCM模块实现多路信号传输实验。设备采用开放式结构设计，关键测试点均设有观测端口，便于使用示波器等仪器进行波形分析。236
Educational Features
Distinguished by its didactic flexibility, this system supports progressive learning through three experiment tiers: basic verification (e.g., sampling theorem validation), functional implementation (such as frame synchronization extraction), and system integration (like constructing FSK communication links). The hardware platform s transparent design reveals signal characteristics at critical nodes including baseband shaping, modulation output, and decoding recovery stages. Special emphasis is placed on hands-on experience - students can actively adjust parameters (carrier frequency, code rate) to observe corresponding waveform changes. The equipment s compatibility with standard lab instruments (oscilloscopes, signal generators) further enhances experimental exploration depth, making it suitable for curriculum experiments, course projects, and innovation competitions.569
