A discrete-time causal filter is described by the following difference equation.
A simple linear filter for simulation of echo-effect can be described by the following equation
How can I represent the above equation in code?
syms x(n) y(n)
eq = y(n) == c*x(n)+(1-c)*x(n-P)
Can I use syms function for n x and y.
P and c are known
Also I want to transform from difference equation to tranfer function. Can I use the function ztrans() for that?
Thanks in advance
