I need to find a) Find the transfer function. b) Give the impulse response. d) Sketch the frequency response. How to do it?

[n] = x[n] - x[n-1] + x[n-2]

Okay. What is your specific question about where you're having difficulty?

Try this:

z=tf('z',0.001);
Gz=1-z^-1+z^-2;
%%transfer function
Gs=d2c(Gz,'tustin')
%%impulse response
figure(1);
impulse(Gs)
%%frequency response
figure(2);
bode(Gs)

Do you have Control System Toolbox installed? Type

ver

in command line and paste the output here.

Hey thank you so much. I got the impulse and frequency response output. But i am not getting transfer function output as I don't have the tool box installed. I have the 2019a version. Is there some another approach to it?
