The filter design process involves identifying coefficients that match the frequency
response specified for the system. These coefficients determine the response of the
filter. You can change which signal frequencies pass through the filter by changing the
coefficient values or adding more coefficients.
Traditionally, designers have been forced to make a trade-off between the flexibility of
digital signal processors and the performance of ASICs and application-specific
standard product (ASSPs) digital signal processing (DSP) solutions. The Altera DSP
solution reduces the need for this trade-off by providing exceptional performance
combined with the flexibility of FPGAs.
