Abstract :
In this paper we show the implementation of a digital control interface oriented to work in a microprocessor environment like Personal Computers, using VLSI Altera chip and standard circuits to generate the voltages that a continuous-time nonrecursive FIR filter needs to fix its coefficients in order to be closed to a specific response. Also we show an algorithm approach based on the LMS technique to get the FIR coefficients
