Hi, i'm new in DSP and i have solve some problems, here is the problem:
Given a causal FIR filter described by the following equation:
y[n]= x[n]-2x[n-1]+3x[n-2]
a) Find the filter impulse response Answer:h[n]=?
b) Using MATLAB find the output when the input to the filter is x[n]=[1 -3 4 0 5 6 1 -2 3]
Answer: y[n]=?
