The given difference equation is Attached.
I have to plot the Magnitude Response of the Filter.
I have searched a lot about these types of Difference equations, and their Magnitude response in MATLAB. But, I found it nowhere.
Please help me on how to do this.
At least provide me with an approach of doing this.
I shall be very thankful for any kind of help.

1,Set up Z transform
Y(z)= .33.z.x(z) +.33.x(z) + .33z^-1.x(z)
2. Obtain impulse transfer function
Y(z)/x(z)=H(z)= .33(z+1 +z^-1)
3. ZT to FT
set z=e^-(jw) to get H(e^-jw)
4, You can get with w= [-2pi to +2pi }
magn response = |H(e^jw)|
phase response also if needed from atan(Himag/Hreal)
Good Luck
Cheers
