I just study signal processing and I have some questions.

1. How to find impulse response h[n]$$h[n]$$ sequence of the system if I have x[n]$$x[n]$$ and y[n] $$y[n]$$ (input and output) sequences? Hope there is a formula to do that.
2. How to find x[n]$$x[n]$$ input sequence if I have h[n]$$h[n]$$ and y[n]$$y[n]$$?
3. Is it possible to find x[n]$$x[n]$$ if I just have set of y[n]$$y[n]$$ values, but I don't know impulse response h[n]$$h[n]$$? How to do that if so?
