Abstract
A 2nd order, low-pass, tunable RC-active filter has been developed. A frequency tuning over the entire audio range and a gain variation over three orders of magnitude, together with all the intermediate values, is readily achieved using segmented resistors. A procedure for frequency and gain adjustment in the filter circuit is also presented.Keywords
