For at least four decades, dual-slope integrating A-to-D conversion has formed the core of most every digital multimeter and many industrial and instrumentation applications besides. Elegant in its ...
Part 2 of this series showed how a dual-slope integrator could fix the major limitations of a single slope converter, and I received several e-mails in response (August 28, p. 18, ED Online 19512).
In my previous column, I took a historical approach to delta-sigma modulation with the single-slope converter (May 8, p. 18, ED Online 18747). Jim Williams of Linear Tech responded, and he sent me a ...
