UFOview story

http://forum.allaboutcircuits.com – I hadn't seen one for 60+ years, until Dec. 3, 2013. Mine was a single orange ball, glowing, but emitting zero rays, slowly rising in the Southwest, around 11:00 PM. It was a lot bigger in diameter, so it must have been closer than I first thought. Here's a video from Australia, of 4 of the same type things: http://www.youtube.com/watch?v=UeC0ZX3-80A#t=205 Ever witnessed a UFO? (Embedded)

Pspice simulationview story

http://forum.allaboutcircuits.com – Hello, I have set a signal with the VPWL. I am using voltmeter to see what kind of signal I have set up in VPWL. If I am adding a 10k resistor under VPWL source, it is changing my signal which comes from VPWL source. Could somebody explain me why it is happening? If I change any other parts they dont affect my VPWL source. Uploaded with ImageShack.us (Embedded)

ADC sampling rate and clock rateview story

http://forum.allaboutcircuits.com – Hello, I'm new to ADC/DAC world but has been reading up a lot on them lately. However one thing is still confusing that is how to calculate the range of a clock input to the ADC from a given spec like a sampling rate of 1.25Mbps. What is the formula to calculate it? It seems to me that another given spec like N bits is also needed. Thanks (Embedded)
