impulse response matlab

[dev_000]

can plz anyone tell how to do this in matlab??
obtain the filtered ouptut of an FIR filter whose impulse response is {0,0,0,1,0,0,0}(origin at 1) and input{1,2,3,2,1}(origin at 3)

matlab impulse response

You can find out the solution theoretically, because your impulse response is just a dirac function at n = 0. So, the output of the filter will be the same as the input.

Take a look at the code:

h = [0,0,0,1,0,0,0];
x = [1,2,3,2,1];
y = conv(h,x);

Note: the filtering process is actually a convolution, so you can use the conv function to do what is needed.
