Engineers targeting DSP to FPGAs have traditionally used fixed-point arithmetic, mainly because of the high cost associated with implementing floating-point arithmetic. That cost comes in the form of ...

Tektronix calls its TPS2000 DSO line the first to include four-channel units that accept floating differential inputs. The lunchbox-sized scopes operate for as long as eight hours from internal, ...

Digital engineers learned long ago that they should not leave unused inputs unconnected. CMOS chip inputs might float up to some midpoint voltage and turn on the output stage, but that would have a ...
