Paper Abstract
The paper describes a design, test circuit and preliminary test results of a programmable filter dedicated to photoacoustic experiments. The filter was implemented as a state variable filter with independent digital control of top and bottom corner frequencies as well as quality factor. In order to perform frequency response measurements a dedicated miniature automatic measurement system was designed. The system was based on digital direct synthesis of the input sine wave and true-RMS detection of the output signal.
