Abstract :
A digitally programmable active filter circuit which can function as a low-pass filter, high-pass filter, bandpass filter, band-reject filter, all-pass filter or a phase shifter network with a direct interface to a microprocessor is presented. The hardware and software details of the filter configuration are presented, and the filter response is discussed. A typical microprocessor interface is shown
