I knew I would probably have to use some analog hardware to output the audio and video unless I used pulse-width modulation, in which case I would only need a low-pass filter.

This thesis introduces the design of high performance analog test interface of BDS circuit board test system. It emphasizes the design theory, hardware architecture and anti-jamming measure.

Described are the design thought, technical implement and hardware disposition of the analog input module for the microcomputer network control unit XDU of the car function grade on EMUs.
