6.976 包括高速通訊系統的電路和系統層級設計問題，主要集中在無線和寬頻帶資料連結應用。其中在電路方面幾個主要的主題包括：傳輸線、高速與低雜訊的放大器、航向控制振盪器、高速數位電路。而在系統方面主要的主題包括頻率合成器、時鐘和資料恢復電路、GMSK（高斯最小位移鍵控法）收發器。學生除了學會上述專案的分析方法，還將獲得許多在SPICE類比電路和CppSim（一個客製化C++模擬器）系統進行電路模擬的實作經驗。

6.976 covers circuit and system level design issues of high speed communication systems, with primary focus being placed on wireless and broadband data link applications. Specific circuit topics include transmission lines, high speed and low noise amplifiers, VCO's, and high speed digital circuits. Specific system topics include frequency synthesizers, clock and data recovery circuits, and GMSK transceivers. In addition to learning analysis skills for the above items, students will gain a significant amount of experience in simulating circuits in SPICE and systems in CppSim (a custom C++ simulator).
