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
教學(xué)功能特點(diǎn)
該實驗箱突出理論與實踐結(jié)合的教學(xué)價值，通過創(chuàng)造設(shè)計性實驗培養(yǎng)學(xué)生系統(tǒng)思維能力。其硬件平臺可清晰展示通信系統(tǒng)各環(huán)節(jié)信號變換過程，如PCM編譯碼單元能直觀呈現(xiàn)語音信號數(shù)字化處理流程，而數(shù)字調(diào)制單元則完整演示了基帶信號到頻帶信號的轉(zhuǎn)換機(jī)制。實驗內(nèi)容設(shè)置遵循由淺入深原則，從單一技術(shù)點(diǎn)驗證逐步過渡到復(fù)雜通信系統(tǒng)搭建，例如通過組合時分復(fù)用與PCM模塊實現(xiàn)多路信號傳輸實驗。設(shè)備采用開放式結(jié)構(gòu)設(shè)計，關(guān)鍵測試點(diǎn)均設(shè)有觀測端口，便于使用示波器等儀器進(jìn)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
