  1. Circuits Oscillators Analog Devices AD8475 ADA4899-1 ADCMP601 ADG736 ADR431
    Engineers have long used function- generator circuits employing analog integrators and high-hysteresis comparators. The outputs of these circuits often depend on variations in temperature, power-supply voltage, load, and parts. However, you can ...

  4. A common problem that arises when you design lowpass filters for signal conditioning is the filters' effect on the system's time-domain response. Because pushing the cutoff frequency lower slows the step response, the system may fail to ...
