A 23 Hz sine wave is generated with Arduino (PWM + RC filter). The signal is sampled at different frequencies (12, 20, 26, 46, 92, and 120 Hz). MATLAB is used to plot time-domain signals and compute ...
A collection of Arduino-compatible digital filter classes used in Vulintus devices' firmware. This library started as a stripped-down fork of Jon Driscoll's "Filters" library, but now differs somewhat ...
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 ...
Do we really need another design tool for Sallen-Key filters? Aren’t there enough [i] [ii] [iii] [iv] [v] already? Obviously, you and I think that there’s something more to say on this topic, or you ...
