The frequency where the open-loop transfer function is at unity gain is called the crossover frequency. With switching frequencies in the megahertz region it is not uncommon to have crossover ...

Electronic control logic and system components are described that are used with a venturi carburetor to accomplish the fuel metering required in a closed loop emission control system. Special open ...

Once the open-loop transfer function is modeled, it’s necessary to design the frequency compensator such that it achieves the best performance possible. Because the frequency response of the above ...
