Kỹ thuật thông tin số

Giới thiệu Kỹ thuật thông tin số

Bộ thực hành xử lý hầu hết các vấn đề của truyền thông số digital. Cung cấp thiết bị, tư vấn bởi Lidinco. Ngoài ra chúng tôi còn cung cấp các bột thực hành viễn thông - thông tin khác

Digital Communication Technology" discusses all topics of digital signal processing. Additionally attention is payed to the realisation and function of a fiber optic transmission system. Emphasis is laid upon the applications of PCM technology, e.g.: transmission of voice signals with real telephones, sound cards, CD-player etc.

Chủ đề:

• Caracteristics of pulse carriers
• Generation of PAM
• PAM (natural)
• PAM (S&H)
• PAM spectrum
• Over sampling / under sampling
• Aliasing
• Shannon theorem
• Pulse code modulation (PCM)
• Quantization linear and nonlinear
• Compression / expanding
• Code errors
• Time division multiplexing (TDM)
• Synchronization
• Quantization noise
• Difference pulse code modulation (DPCM)
• Optical signal transmission
• Signal transmission by wire (coaxial line / two-wire line)
• Simplex / duplex communication

Options

• Transmission of voice (requieres external signals as CD player, telephones etc.)
• Linear and nonlinear quantization and the influence on the quality of voice
• Duplex communication
