Can i implement FIR filter in FPGA using fixed point number..
I referred various FIR filter implementation in FPGA all have used integer coefficients for their implementation and i am interested to know the difficulties of using fixed point numbers.I knew fixed point numbers utilize more hardware.
I understand fixed point number is scaled and rounded to get integer values from various tools(FDAtool) hence some information will lost..Ultimately this will alter the filter response(cutoff,passband,stopband)
am i correct?
if it is possible to implement in fixed point can anyone compare the accuracy of integer FIR implementation and fixed point implementation?
pls clarify ..
