Although it contains six passive components, the transfer function of the section is fully defined by only two parameters: the resonance frequency F 0 Hz, and the quality factor Q. Therefore, there ...

A research team from Singapore has successfully designed the world's smallest on-chip low-pass filter which is 1,000 times smaller than existing off-chip filters.

It is useful to remove any undesired higher frequencies and is widely used as an anti-alias filter for an input to an ADC or as a reconstruction filter to smooth out a DAC generated output. The ...

Low-pass filtering further transforms the spectrum through a multiplication by the filter transfer function H n (ω). The demodulated signal Z (t) contains all of the frequency components around the ...

But generating a smooth voltage in this way takes just a few more parts. [Scott Daniels] spent some time discussing the process of smoothing a PWM output by using a low pass filter.
