I am implementing IIR Filter in verilog
with equation
y
=a*x+(1-a)*y(n-1)
a is floating point no with 5 bits
x is integer with 7 bit input .y is 12 bit with 5bits
floating and 7 bit integer part
I used 2's complement logic for 1-a.
I did multiplication by shit and add.I used rounding function
for y with refernce .5.My problem is i am getting limit cycle
oscillation.How to solve this as I am running out of time for
solution.Help me Thanking you
