Circuit diagram shown below is a first-order low-pass Butterworth filter that uses RC network for filtering. Loading of the RC network is avoided by using the Op-Amp which is configured for ...

He also added a low-pass filter and a comparator to clean up the signal into a nice square wave, ... My revised filter circuit with off-the-shelf component values.

My revised filter circuit with off-the-shelf component values. ... the example I used was the characterisation of a 7th-order 30 MHz low-pass filter. ... I appreciate this basic tutorial, ...

For example, a programmable second-order, low-pass Butterworth filter with a corner frequency ranging from 200 Hz to 20 kHz can be designed by setting C1 = 0.022 µF and C2 = 0.1 µF.

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

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.
