Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications.

A low-pass filter is the most common filter found in data acquisition systems. Typically this type of filter is used to reduce analog-to-digital converter (ADC) aliasing errors and noise outside the ...

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

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.

If needed, the circuit can be programmed as a high-pass or low-pass filter as well (see the table). Analog Devices' AD844, a monolithic current-feedback op amp, forms the heart of the circuit (Fig ...
