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 ...

A common requirement in data acquisition system signal paths is a low-pass filter.

He also goes on to add an FIR low pass filter to cut off the ringing which was consequent of adding a feedback loop. [nebk] uses Matlab’s filter generation tool for the LP filter which he ...

Figure 2 A Sallen-Key low pass filter showing all noise sources. It’s convenient to think in terms of the signals in the figure as being volts and amperes per square root Hertz rather than of volts ...

Low-Pass Filter Design and Applications Publication Trend The graph below shows the total number of publications each year in Low-Pass Filter Design and Applications.

This monograph describes the theoretical and practical details of the design of a very linear phase-shift low-pass filter intended to remove noise and other irrelevant information above ...

There’s also a low-pass filter that’s controlled by a couple of light-dependent resistors, which can be played by blocking them off with a fingertip.
