This analytical and graphical technique allows engineers to determine, in closed form, the output of an RC filter driven by a PWM pulse train. It is based on the principle that current and voltage ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

Part 4 of this series recognizes that, in spite of all efforts to keep the EMI and RFI from corrupting the sensor signals on their way from signal source to the signal conditioning instrumentation.
