Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...
This study considers trade-offs between timber harvest and carbon
sequestration on National Forest and other public lands by contemporaneously linking
a model of public harvest and inventory to a carbon accounting system. The public
harvest model treats three harvest scenarios. The first minimizes the cost of meeting
harvest requests that...
