My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

This application report describes a dc controlled low-pass filter circuit using LM3046. The cut off frequency can be varied by varying the capacitance of the low-pass filter. In medical ultrasound ...

The FMS6413 (single-channel) and the FMS6414 (dual-channel) video line drivers include video low-pass filters for standard definition composite and S-video applications. The monolithic devices combine ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...
