Real time digital pulse shaper with variable weighting function

Real time digital pulse shaper has been developed that provides digital control of the synthesized weighting function (WF). The shaper can synthesize in real time shapes that are optimum or near optimum in the presence of 1/f noise. Other pulse shapes including trapezoidal and triangular can be realized. The WF is synthesized by algebraically adding a concave and a convex pulse shapes. The shaper is implemented in a single chip and is a part of a spectroscopy system on a programmable chip.
