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

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
