The Field Programmable Gate Array (FPGA), were created in order to execute and
implement projects requiring high-performance circuits, they are very useful for
debugging microprocessors and Application-Specific Integrated Circuits (ASIC),
unlike microcontrollers have the advantage of changing its hardware with program
codes, the FPGA´s computing power and speed, make them suitable for processing
signals.
This project shows the design and implementation of finite impulse response (FIR)
digital filters, such as, highpass, low pass, pass band and rejects band. Using the
Altera’s Cyclone III FPGA’s for Audio signals and MATLAB for the calculating and
simulating the behavior of the filters; the FPGA’s programming was done through
blocks language in Simulink. Measurements, data registering were realized to obtain
graphics and to compare the simulation versus the theoretical data. The filter that has
approached more to the simulation behavior is the FIR rejects band with an error on
the frequency response’s magnitude of 1.82 % with a variance of 7.53·10-6 % and
an error on the frequency response’s phase of 1 % with variance of 0.64 %. |
