# A Makefile which goes through the design process
# for a 4th-order modulator with an OSR of 64.
# To design another modulator the designer must re-code 
# the sim.c program (using the results from realize)
# and change scaling values (determined from the unscaled
# xmax simulations.

OSR= 64
k= 2
w0= 0
# if you use a different w0, you should change the f= argument
# in the simulations which determine xmax. Also, increasing the
# number of time points to 100000 is probably wise.
