| Question about cable properties Posted: 08 Jul 2011 07:14 PM PDT I am a medical technologist not an engineer. I work in a sleep lab. The sleep recording equipment is comprised of an EEG headbox which digitizes the signals and sends them to an amplifier control box which then transforms the signals to travel over ethernet. The headbox is powered by the amplifier control box. The manufacturer of the equipment states the cable between the headbox and the amplifier control box has a limit of 25 feet. I have a need to extend the length of the cable to 75 to 100 feet. I took the headbox apart and the connector on both ends of the cable is a D-sub HD26. Each conductor is 26AWG. Only 16 [1-16] of the pins are being used. I placed my ohmmeter on the cable and its resistance is 1.3ohms with a length of 25 feet. I am worried about lengthening the cable. As I understand it, the resistance of this cable every 25 feet is 1.3 ohms. So. What can you suggest? I've been studying this all day and need some good advice. Would a 75 to 100 foot 24AWG conductor cable be sufficient to replicate the specs of the 25 foot 26AWG conductor cable or do I need to use a 75 to 100 foot 20AWG cable? I just do not want the equipment to encounter any problems by increasing the cable length. Thanks RPSGT88 |
| Need Suggestions for FYP on Image Processing Posted: 08 Jul 2011 11:39 AM PDT Hi Everyone! I am a student of Electronics Engg. in 6th semester. I've to decide my FYP based on image processing applications. The application is to be implemented on any hardware platform like FPGAs, Texas DSP kits or using GPUs. I've already made a small project on target tracking through FPGA using real-time video processing. I need some latest ideas/research projects, any industry-specific or product-based project. I would be very glad and thankful if anyone could help me in this regard. Thank you! |
| choosing the elective subjects Posted: 08 Jul 2011 11:35 AM PDT please help me in choosing the subjects: operating system,image processing(1 elective group) and out of real time systems and data structures(other electiv group) i am interested in the multimedia field . please help me in choosing the suitable elective |
