function twiddlegen_rc(N,tbits)

%   twiddlegen_rc(N,tbits)

%       Thi s function generates all the roms needed for an

%       FFT  of N points.  Twiddle factors are tbits wide.

%

%       This program uses:

%       romgen_rc.m

%            |-frac2bin.m

%           |-writeb in.m

numpoints=N;

rnum=1;

while numpoints>4

    romgen_rc(numpoints,N,tbits,rnum);

    rnum=rnum+1;

    numpoints=numpoints/4;

end
